Joel McHale, Christina Applegate & The ‘RHOBH’ Cast Celebrate NBC [PHOTOS]

The NBC stars were out in full force last night at the NBC Universal TCA 2011 Press Tour All-Star Party celebrating the forthcoming season.

Community co-stars Ken Jeong, Joel McHale, and Chevy Chase were clowning around on the red carpet at NBC’s TCA party.

The always beautiful Amber Heard from The Playboy Club looked drop-dead gorgeous in a slim black halter dress and an updo that showed off her seemingly perfect bone structure.

The star of Up All Night, Christina Applegate was at the event, while Will Arnett and Maya Rudolph were not present (Maya just gave birth a few weeks ago).

NBC president Robert Greenblatt told reporters at the Television Critics Association’s summer press tour that Reagan and Ava’s workplace has been altered from a public relations firm to a daytime talk show.

“We decided to change the workplace altogether, to give Maya a better platform to do her thing,” he explained. “[Ava is now] a larger-than-life talk show host, and Christina will play her producer.”
