Why is Cameron Diaz pulling a Britney? Is Justin Timberlake’s current girlfriend, Jessica Biel, next? Maybe if she scores a part in a movie about cancer. Cameron “shaved” her head in her upcoming film, “My Sister’s Keeper,” about a child who is “engineered” so that she can give her cancer-striken sister a kidney to save her life. Cameron plays the mom in the movie, so maybe she’s doing a sympathy shave. Regardless, Cammie D fans can rest easy knowing she still has her flaxen locks and didn’t go looney tunes like Brit. FYI, the film’s trailer is after the jump…

This week, Britney Spears stopped performing in the middle of her Vancouver show because the venue was allegedly full of cigarette and marijuana smoke. Spears (a smoker) claimed the funky air was making her and her crew gag. She returned to the stage 45 minutes later, and finished the concert with a constructive, “Thanks Vancouver. You were wonderful. Drive safe. Don’t smoke weed!” [Hollywood Rag]

Pink surprisingly jumped on the circus-themed concert bandwagon with her “Funhouse” tour costumes. When a wannabe badass like Pink starts jumping on a trend, it’s time to retire it. So, we implore these concert producers to stop with the three-ring, freak show madness. Even Katy Perry refused to do the circus thing for a recent concert, saying, “That’s really being done by a lot of people right now.”

According to a study published in the journal Archives of Sexual Behavior, the length of time a man looks at a women the first time they meet can be an indicator of how he feels about her. So, next time you go on a blind date, bring a stopwatch. The study, which tracked eye movements of 115 students as they spoke to actors and actresses, found that men looked into women’s eyes for an average of 8.2 seconds if they thought they were beautiful. When they rated a woman as less attractive, they only looked at her for around 4.5 seconds. Now, I’m not sure if you’re aware, but eight is a lot of seconds to be looking at someone. If a random guy in a bar looked at me for that long, I might think he had a staring problem. To give you an idea of how long a guy will look at you when he thinks you’re hot, listen to this clip from the Britney Spears song “If U Seek Amy,” which is eight seconds long. [Telegraph]

The OctoMom, Nadya Suleman, has created a lot of drama, condom use, and diaper sales, but now she’s also inspired art! Daniel Edwards, best known for his sculptures of Britney Spears giving birth doggy style on a bear skin rug and Paris Hilton’s anointed autopsy with dog Tinkerbell pawing her body, has taken another pop culture icon, the OctoMom, and made her even more plastic. Pepto Bismol pink String Of Babies has Nadya Suleman wrapping her tentacles around eight baby heads and one giant phallic baby bottle.  But we all know, she’s really got a hold on the media!

Slate has uncovered shocking evidence that Britney Spears’ songwriting abilities are maybe, just a tad, unoriginal. Her most recent single, “If U Seek Amy,” is a play on words that, when said quickly, spell out, um, something dirty. Best of all, the way in which the phrase is used in the song, doesn’t really make sense. “All the boys and all the girls are begging to if u seek Amy.” However, previous uses of naughty wordplay like this are everywhere and no doubt inspired Brit. “If You See Kay,” apparently, has been a song put out by a bunch of artists, including one who admitted that he got the reference from James Joyce, who wrote in Ulysses:

If you see kay
Tell him he may
See you in tea
Tell him from me.

The old, blond hair whipping Britney is back and she wants you to find some chick named Amy. Not sure why, she hasn’t explained. Anyhoo, in the video for the song, Britney is totes having a raging, sexual party with some girlfriends, and they dance together, and everyone looks HOT. Then, all of the sudden, things get kind of misty and Britney’s hair is shorter and she’s rockin’ some soccer mom digs, and is carrying a pie and there are some kids and OMG, what do you think it means? Is Brit saying that all the boys and all of the girls who are begging to “if you seek Amy” don’t know the real her? That’s deep yo. Also, pie sounds yummy.
