Tom Cruise kept close to Katie Holmes during the beginning of the night chatting with Annette Bening and Warren Beatty, with a lot of "congrats" to Annette being thrown around (we know she'll be keeping the convo light during this awards season).

Brit-pack cutie and Robert Pattinson BFF Andrew Garfield was in attendance with his girlfriend, Shannon Woodward, and mingled with fellow Social Network pal Armie Hammer.

Joe hung tight with an agent-looking gal for most of the night, and steered clear of some of the single ladies attempting to vie for his attention.

Jonas was heard explaining to pals that Ash was busy filming Breaking Dawn in Louisiana and he was missing her a lot.
