WTF?!?

Fergie looked like an extra from "Tron" in her futuristic skeletor-inspired jumpsuit while performing at the the Black Eyed Peas' "The E.N.D." concert in Philadelphia. More like the end of fashion!

So you either love her or hate her. Personally, we love Lady Gaga's giant rose headdress ... it's the multi-patterned lace from head to toe that makes us a little dizzy, and a little itchy too. At least it was for a good cause -- the pop star was attending the M.A.C. Viva Glam launch in London to raise funds for AIDS research.

Usually a trendsetter in her own right, burlesque star Dita Von Teese looked like a faded carbon copy of Gaga while at the Just Cavalli Cointreaupolitan cocktail party in Milan. Her lace ensemble also reminds us of Britney Spears' horrific Grammys getup.

The bat-out-of-hell Alexandre Vauthier Spring 2010 couture jumpsuit Rihanna rocked at the Echo Awards in Berlin was actually kind of cool. It's the bowl haircut that's killing us.

Oh, Kelly, you were the star of New York Fashion Week, and now you commit this 'old lady lavender' crime against your own tresses! Is it a transition color? Please say it is.

Lindsay Lohan somehow managed to wrangle an invite to the Roberto Cavalli party in Milan, and she turns up like this? A ratty (hopefully) faux fur vest and sequined fisherman pants that look like they came from the back of grandma's closet won't cut it in Italy, LiLo.

"The Bachelor's" Jake Pavelka showed off his inner dork in an unflattering baby blue turtleneck while out at Koi in LA with his brand new fiancee Vienna Girardi. See that look on her face, Jake? She's like, "Yep, I'm stuck with him."

Kara, we know Ellen's getting all the attention on "Idol" these days, but wearing a wonky Vera Wang gown to Wang's own store launch isn't going to win you any more fans! Neapolitan ice cream anyone?

Let's hope that "Up in the Air's" Anna Kendrick opts for something a little more flattering than this frumpy Z Spoke by Zac Posen number to Sunday's Oscars.

Michelle Williams, you stole that ghastly gold sequined jacket from Beyonce's mom, didn't you?

Spice Girl Emma Bunton looked like a kid playing dress-up in her overwhelming print frock at the Children's Champions 2010 Awards in London.

"The Real Housewives of New York City" star Kelly Bensimon looks great ... until you get to the three inches of fishnet between her dress and her opaque tights. Those three inches lost you the prize, honey.
