Va-va-voom!

Britney Spears made her red carpet return for the Southern Style St. Bernard Project Event in Beverly Hills on Wednesday. Wearing a figure-hugging Herve Leger by Max Azria dress, the "Till The World Ends" singer, 29, was joined by her agent beau of two years, Jason Trawick.

The outing marks the first time that Spears and Trawick have stepped out as a couple on the red carpet. "We have such a great time together!" Spears recently told Us Weekly of Trawick, 39. "He makes me laugh, and we are so comfortable being ourselves." See more photos from the star-studded event.

Guests including Selena Gomez, Kellan Lutz, Shenae Grimes, Hilary Duff and Mike Comrie, Kim Kardashian and Kelly Osbourne all sipped on Spears' sweet tea; the singer's father, Jamie, catered the charity event.
