The star, along with many of her fellow nominees that morning, came straight to the festivities after attending the Academy's annual Oscar luncheon.

Amy Adams, who is no stranger to attending the star-studded class photo, opened up to ET about the experience which she still feels is a bit surreal.

"Just to be on the bleachers with everybody and to hear everyone's name called, it's always overwhelming to realize the company you're in," said Amy.

Like Jessica, The Master star is mixing it up, as far as her dates go, during the award show hoopla.
