The Stars Party at the OK! Pre-Oscar Bash

It was a night of glitz and glamour at the exclusive Feb. 22 party OK! threw at Hollywood's Emerson Theater to celebrate the Oscars!

Kristin Cavallari, rocking a sexy black leather dress, was one of the first celebrities to arrive.

Kendra Wilkinson-Baskett looks great! Her secret to feeling good, too? "Eat a lot of antioxidants, drink a lot of green tea with lemon, flush all those toxins out," she told OK! on the red carpet. "It just makes you feel cleaner and lighter."

Kendra couldn't wait to dance once inside the OK! pre-Oscar party. Her favorite move? "Definitely the booty shake! My infamous booty shake," she said.

Taylor Armstrong told OK! how she's bettering her relationship with John Bluher. "I’m working on sharing my feelings in the moment and speaking my mind and not allowing resentment to build up," revealed Taylor. What does she do with John otherwise? "Make out!" she joked.

Is it true Slade Smiley gave Gretchen Rossi an engagement ring? "That’s so funny," the "RHOOC" star told OK! at the pre-Oscar party. "I wear this ring that I got from my late fiancé Jeff Beitzel all the time. Sometimes it’s a big deal, and sometimes it’s not talked about."

Taylor Armstrong's "life coach" Melanie Mar hung out with her "RHOBH" pal all night. "You really can’t be on all the time," she said of the way Taylor is portrayed on the show. "It’s your life! The good, the bad, the ugly."

Season 10 "American Idol" Pia Toscano told OK! she's rooting for the show's girls this year—especially Angela Miller and Kree Harrison, who she calls "phenomenal."

Lilly Ghalici partied in a curve-hugging leopard-print dress to show off what she thinks is her best asset. "I love my butt! I’m proud of it—I do a lot of squats and lounges," the "Shahs of Sunset" reality star told OK!

"I love to see the variety of style and fashion and all of the different articles," Sheana Marie from "Vanderpump Rules" says of OK! "It’s amazing!"

Redfoo of LMFAO and tennis champion Victoria Azarenka had a blast. Then again, they always do when they're together. "We really enjoy each others' company," said Victoria. "We can talk for hours and time goes by so quickly."

Mercedes “MJ” Javid and Golnesa “GG” Gharachedaghi from the "Shahs of Sunset" showed off their legs while checking out Vaseline Spray & Go Moisturizer, one of the party's sponsors.

It was a "The Hills" reunion for Stephanie Pratt and Kristin Cavallari.

The OK! pre-Oscar party was a hit thanks to sponsors Vaseline Spray & Go Moisturizer, UV Vodka, SexyHair, Le Vian, Hydroxycut and Wines by Wives!
