Because celebrities haven’t taken over every millimeter of your existence quite yet, some intrepid folks of note are coming to an iPhone near you. That’s right, having your favorite celeb at your fingertips 24/7 is the wave of the future. Last week, Britney Spears joined the trend, launching her very own iPhone app, “It’s Britney!” For the modest cost of $1.99, you can easily get messages, news, photos, and Twitter updates from Brit. There is even a sparkler feature, so when you go to her next show you can hold up your phone instead of a lighter. The best feature though, in my opinion, is the Shake Shake Shake option, which makes your phone yell, “It’s Britney, bitch!” every time you shake your phone. All in all, this sounds like ... a big waste of two dollars. [MTV]

After the jump, some more celebrities getting in on the app game.

Has someone hacked Britney’s Twitter or is she really discovering a fondness for Lucifer? [Twitter]

It’s not often that I agree with John Mayer, but even I have to admit he had a point when he tweeted: “If you’re shocked that Britney was lip-syncing at her concert and want your money back, life may continue to be hard for you.” You see, Britney Spears is on the Australia-leg of her “Circus” tour, and some fans and Australian government officials are upset that she lip-syncs during the performances. “It was so impersonal. She did not interact with her audience,” says dissatisfied fan Wendy Di Renzo, who told People she paid $148 for her ticket. “There were no big TV screens projecting the action, so if you didn’t know Britney, you might have even doubted it was her.” Australian press reported that fans walked out of her shows after a few songs, saying it was boring, mimed, and stiff. The Fair Trade Minister of New South Wales even suggested that concert tickets carry a disclaimer about whether artists lip-sync or prerecord parts of their concerts. But anyone who is a true Britney fan should know that she very rarely sings live during her performances. Her voice isn’t strong enough for her to sing while dancing and performing acrobatics, so fans have to decide whether they want to be visually entertained while hearing her music. And what fun is a pop music concert if the artist sits in a chair while singing the whole time? [Reuters, People]

Out-there pop singer Har Mar Superstar—who bears a striking resemblance to Ron Jeremy—wrote a song for Britney Spears called “Tall Boy.” The tune was about having sex with tall men and drinking cans of beer, so it’s not a big surprise that BritBrit passed on it. But Har Mar Superstar thinks this was, like, the best rejection ever. He put “Tall Boy” on his upcoming album, Dark Touches, and said, “It’s my favorite song I’ve written.” Actually, I could totally see Britney busting out this techno-esque tune while wearing some racy outfit. She’d probably just add a few electronically enhanced groans. [Spinner]

Lots of musicians perform hand-me-down songs. Here’s a collection of songs that were originally meant for another artist.

Just as suspected. Britney Spears just released the video for her new song “3,” which you’ve probably been hearing everywhere since it’s sitting at the top of the Billboard music chart. And from that little snippet where she’s being pulled back and forth by two dudes in body paint, I think it’s safe to say that the song is definitely about threesomes rather than, say, math. Sure seems like Hollywood’s gone threesome-crazy, no?

• Britney Spears’ mom says the singer’s new beau/agent Jason Trawick is The One. [Us Weekly]—Wouldn’t it be great to see Britney in love again?
• Lindsay Lohan shrugged off rumors that she got it on with Balthazar Getty in a club the other night, saying “You think I would do that to Sam [Ronson]? I love her.” [Dlisted]—When is this pathetic child going to realize that she can’t love someone until she loves herself enough not to be an embarrassment?

• For some strange reason, Britney Spears thinks she should wear booty shorts with knee-high socks and sneakers. [Hollywood Tuna]—Maybe she’s decided to switch her career to soccer player.
• Bethenny Frankel of “The Real Housewives of New York City” has reportedly been replaced by socialite Sonja Morgan because Bethenny is supposedly getting her own show on Bravo. [Dlisted]—When does the show start? When?

Just when “Circus” and “Womanizer” lost all their appeal, Britney Spears debuted a brand-new single this morning on the Elvis Duran Show on Z100 at 7 a.m. Because that’s just the time we all want to hear dance music? Anyway, this song is called “3” and it’s off her greatest hits compilation, “The Singles Collection,” which will be in stores in November. Enjoy, and start speculating what it’s about.

Ever wanted to know what a megastar spends in a month? Lucky for you, Britney Spears’ credit card bill for the first 11 months after her dad took control of her finances has been leaked to TMZ. Wait, Britney only has one credit card? Time to diversify, girl. Also, considering the insane amount of my credit card bill over the past year, I’m surprised that BritBrit, who makes zillions, only racked up $112K. After the jump, how BritBrit spent her money this year.

A few years ago, country star LeAnn Rimes was so squeaky clean that she made Sandra Dee look naughty. But over the past six months, that’s started to come apart, between her affair with Eddie Cibrian, subsequent filing for divorce, and multiple moving vehicle snafus. Now, LeAnn is looking a lot more like two other women who started out as wholesome teen stars and grew up into not-so-stable adults. So is LeAnn the next Britney Spears or Lindsay Lohan? After the jump, the parallels between BritBrit, Lilo, and LeAnn. We should probably start calling her LeRi, like, now.

Britney Spears may not always pick the best dudes, but these days she’s gotten craftier with how she picks them. Now that she’s done dating her agent, Britney reportedly flipped through model agency catalogs to find her next beau. She took a liking to Ford model Bekin Trenova, who recently broke up with a Victoria’s Secret model. To get her man, apparently she had him “audition” for a music video. According to a source, “When he got there, there was no camera crew. There was just Britney. She was looking sexy. She made it pretty clear that she was less interested in hiring him than in dating him.” He supposedly thought it was creepy and politely excused himself. This one may not have worked out for her, but why shouldn’t Britney get her men delivered? Men use the casting couch excuse all the time! [NY Daily News]

There are two semi-shocking things about this video. First, Britney Spears is actually singing not lip-syncing. Second, she’s singing Alanis Morissette’s “You Oughta Know” rather, well, awesomely.

Here’s a nonsensical one for you. On Tuesday, three women were supposedly bounced from a Britney Spears concert for ... wait for it ... dancing “too provocatively.” The girls say they were ganked from their seats by security after someone complained about their moves during the song “Get Naked,” causing the girls to miss three songs. I doubt a few girls in a row of seats could do anywhere near as much damage as scantily clad Brit Brit was likely doing on stage. All I have to say is, “Pot. Meet kettle.” [NY Post]

• Britney Spears and her agent-boyfriend are reportedly no longer an item. She told him she needed to stand on her own two feet before getting into a serious relationship. [OK! Magazine]—Let’s see who in her employ she’ll date next.
• Anne Heche revealed what she really thinks about her estranged ex Coley Laffoon: “Can you say ‘lazy ass’ on TV?” [PopEater]
• Rosie O’Donnell hinted that the rumors saying she and her wife of 12 years are heading for divorce are true by writing a really strange poem on her website. [Starpulse]—Someday Rosie will make it in the news for her talents and not for starting fights or her personal life.

I posed nude once. The photographer was a professional and a friend, and the scene was a sound stage. The photos were black and white, and you couldn’t really see anything, as I covered up my naughty bits. It was pretty fun actually, and kind of freeing. If you’ve been wondering what it would be like to be shot in the nude, but you’ll only drop trou for a top-notch photog, this is your lucky day. Rankin has shot everyone from Britney Spears to Kate Moss to Queen Elizabeth II, and his high-gloss images have become iconic. For Rankin Live, he’ll be shooting aspiring nudes on August 29. If you are “feeling frisky” all you have to do is send him an email entitled: “Shoot Me Nude.” The catch? You have to be in the UK to do it.

Everyone’s favorite reformed (?) psycho-in-a-blond-weave, Britney Spears, made an appearance on “Letterman” last night, reading the Top Ten list which, appropriately enough, was titled “Top Ten Ways The Country Would Be Different If Britney Spears Were President.” Wearing a string bikini — and an enormous tropical flower behind one ear — and looking more toned and in-shape than she has in years, Brit-Brit sat atop a Presidential-looking desk and shifted her weight from hip to hip as she read each number. The appearance was certainly less disastrous than past televised appearances (the infamous MTV Music Video Awards, anyone?), but I couldn’t help but think her “charisma” seemed a little canned. What do you think?

Ahh, humpday. Time to woman-up for the remainder of the week and take solace in the fact that while you have to be at work, the only people that care to gossip about you are hovering around the water cooler pointing at you right now. You could be famous and getting pummeled by the rumor mill on a weekly basis! Here are the highlights from the tabloids this week.
