A few short years ago, Kelly Osbourne was known solely for her fashion faux pas, wild hair and makeup, and drug addictions. So why did she pen a style book? Well, as any “Dancing with the Stars” fan will tell you, Kelly has lived through her well-documented fashion mistakes and has learned from them, coming out of the “tough years” very poised. She reveals her style tips in Fierce in a way that only Kelly can, but we’ve got a few takeaways for you after the jump.

Kelly Osbourne has majorly grown on us since her days as a sort of bratty kid on “The Osbournes.” Now that she’s on “Dancing with the Stars,” we’re getting to see a side to Kelly we never knew existed! Last night, she admitted to loving musicals and being disappointed that she didn’t get to play the lead in “Chicago” on stage because she “couldn’t dance.” Watch the clip above to hear how “DWTS” has done wonders for Kelly’s confidence, then watch her and partner Louis Van Amstel do the Charleston—and prove the people who said she couldn’t dance wrong—after the jump.

Kelly Osbourne and her model BF, Luke Worrell, are the cutest couple evah! They’re so friggin’ butt crazy for each other we can’t even make fun of their matching hairdos. Hey, it looked fabu on both of them as they posed on the red carpet for The Hollywood Style Awards (whatever those are). [Los Angeles, 10/11/09]

Sensitive skin types listen up: Kelly Osbourne wants you to know that British body spray Impulse will wreck your skin. She wants you to know so very much that she Twittered a pic of her unfortunate-looking underarm burn. TMI or PSA? [Twitter, 10/5/09]

Kelly Osbourne has a bone to pick with some ladies’ style. The “Dancing With The Stars” contestant was reportedly overheard saying at Teen Vogue‘s Young Hollywood party, “that she was ‘shocked’ at how short the skirts of female partygoers were since they were all so young.” We’re not sure when Miss Osbourne became such a prude, but obviously short skirts make her peeved.

Jealousy? Perhaps. But maybe just a natural reaction. How many times do you walk down the street, check out another woman’s outfit and think, Why? Whyyyy? Why, oh lord in heaven, would you ever wear that? What fashion choices piss you off? A few from us, after the jump.

I have a new favorite genre of daytime television—stars going on talk shows, getting down and dirty about the details of their drug addictions. If you still haven’t seen Oprah’s interview with Whitney Houston last week, please watch now. But today’s contribution to the cannon, Kelly Osbourne on “Ellen” talking about her addiction years, is precious too: “I was so ashamed of myself, I didn’t want to tell my parents,” she said. “My mom was in a relationship with my father for years trying to get him sober and I didn’t want to tell her that now her daughter, too ... I was a full-blown addict by the time we started ‘The Osbournes.’ It was a time when I was suddenly famous, my mom had breast cancer, and my dad almost died in a bike accident. It was a lot for me to handle, and I didn’t handle it very well.”

We’ve already discussed The Shoe that we non-famous people are going all bats**t crazy over, but here’s The Bag of the season, according to Alexander McQueen’s Twitter feed and, um, visual proof— Freida Pinto, Kelly Osbourne, Little Boots and Sam Taylor Wood all wore his Skull Knuckle Duster Clutch to those GQ awards we were discussing yesterday. (On that note, if you haven’t witnessed Kate Moss’ temper tantrum yet, please watch it ASAP.) This shiz is smokin’ hot if, say, you’re into skulls and leather and all that crap (and I assure you, I am), but the problem is that I’m pretty sure the designer’s publicists sent these gorgeous young folks this clutch free of charge, because that’s basically how this system works. Sadly, most of us peons will never quite achieve McQueenian nirvana since the price tag of this delectable little number is no less than $1,895. Check it out here if you want to buy it and/or don’t believe me. Get a much closer look at it after the jump, because you know at least we can look forward to knockoffs coming to an H&M near us soon.

The new season of “Dancing With the Stars” premieres on September 21 and the producers have nailed down a pretty dope cast. We were really surprised to hear that former Republican House Majority Leader Tom DeLay will be sashaying across the stage, along with Macy Gray, Melissa Joan Hart, and Aaron Carter. After the jump, hear what the new contestants have to say. [ABC News]

Kelly Osbourne looked like a Debbie Downer at the “Terminator Salvation” premiere last night. Could her new hairdo be teaching her that blonds don’t really have more fun? If there’s anyone who could turn that frown upside down, it’s gotta be the flick’s butt-kicking stud of a star, Christian Bale. [Hollywood, 5/14/09]

Good thing we weren’t skating alongside Kelly Osbourne, or we’d knock her down and steal those sparkly roller skates. [World On Wheels, Los Angeles, 4/29/09]

“I was on tour with my dad and at every single one of his shows, they hand out condoms. I was about seven or eight and I picked up a packet and was like, “Mum, what’s this?” —Kelly Osbourne [The Mail on Sunday]

“I respect Gwyneth Paltrow, because she covers her babies’ faces – she never lets the paparazzi get that picture. I’m not going to put the Spice Girls down, because I’m a fan, but they took their kids on stage at every single show of that last tour. To be a child of three and have 25,000 girls screaming at you – I don’t think that’s necessarily good. But I’m not a mum, what do I know?” —Kelly Osbourne [The Sunday Times, U.K.]

There’s good news for the pack of nearly a dozen fashion mavens that came to my Halloween party dressed as Amy Winehouse: she’s launching her own line of cosmetics and accessories!  From hair scarves to liquid liner, the vamp style icon has been in talks this week to create products based on her unique look. Winehouse, who just hosted a makeover/sleepover party this week with Kelly Osborne and her goddaughter, has had her praises sung for more than her sweet 60’s style.  The five time Grammy Award winning voice is poised to send boring boho fashion into style rehab. From the looks of all her excited fans, it’ll be straight eye for the queer guy…and gals like me!  [The Sun]
