This must-see style event is scheduled to air tonight at 9 PM (ET) and features Hollywood's hottest designers, stylists and celebrities.

Nicole Richie sparkled in a strapless white Ungaro dress with gold embellishment. "My collection for QVC is inspired by the 60s and 70s and is perfect for the busy multi-tasking woman," The Fashion Star judge said about her new bohemian-inspired line. And while her all-season must-haves include a black blazer and red lipstick, "sunglasses are my go-to for spring," she said. Also on the carpet was George Clooney's arm candy Stacy Keibler, who stunned in a Herve Leger dress. "I love to shop on QVC," she gushed. As for what we can expect to see her in on Sunday at the Oscars? "I have a few options," she said. "This is going to be my first Academy Awards night so I want to make sure I get the dress right."

Lisa Rinna-who also debuted a line with QVC called Belle Gray by Lisa Rinna-arrived with husband Harry Hamlin and mingled with Kathy and Rick Hilton and Kyle and Kim Richards, while Mario Lopez and Courtney Mazza enjoyed date night and divulged that they were well underway with wedding planning. Kim Kardashian said to expect lots of color from the K-Dash for QVC line for spring and Anna Kendrick dished about her new project What To Expect When You're Expecting. "It was weird playing the pregnant girl. There was a lot of bonding over pregnancy on the set," she said.

Inside the party, the stars enjoyed lush surroundings at The Four Seasons with interactive touch screens and displays of gorgeous white roses. A pregnant Molly Sims said her favorite thing about QVC is that "you can find everything you need." However, "the best accessory for any look is definitely a baby bump," she said. Other celebs who palled around inside included Chris Noth, Jamie Chung, and Cheryl Burke.

Also on hand to celebrate QVC's return to L.A. were stylists-to-the-stars Cristina Ehrlich and Mark Zunino who offered tips and tricks for transforming the season's top trends into everyday wear. L.A. designer Rachel Pally was on hand to share her love of fashion and present her debut line. Acclaimed jewelry designers Judith Ripka and Erica Courtney also joined the all-star lineup to put the finishing touches on the ravishing red carpet looks.

To add a distinct touch of Hollywood glam to the evening, QVC enlisted some of its most premier beauty and style experts, including Kate Somerville, Nick Chavez, Ken Paves, Chaz Dean, the bareMinerals team and QVC newcomer Kimora Lee Simmons, who is scheduled to debut her innovative new anti-aging cream. Celebrity favorites Sarah Potempo and Smashbox also lent their expertise by creating all of the models' looks for The Buzz on the Red Carpet - Live from L.A. show.
