Yeh, it’s not obvious in the gif but in the full video it seems that she gets a slightly creeped out look on her face as soon as Modine starts touching her and looks to a couple of places in the audience (presumably her friends) with a “what the hell is this shit?” expression.
She then remembers that she’s on camera and realises that another of her costars is giving a fairly right-on speech, so she tries to suppress the “ick” expression and show her support but doesn’t quite manage to cover up her initial reaction to being pawed on stage while accepting an award.
I can’t say I blame her, to be honest.
