The former Friends star was pictured laughing and smiling on the red carpet on Wednesday night (14 January), as she awaited word on whether she can now add 'Oscar nominee' to her name.
Jen has been widely praised for her role in the gritty drama, giving a harrowing and darkly comedic performance as a chronic pain sufferer who becomes fascinated by the suicide of a young woman in her support group.
She's already received a slew of award nominations – including at the Golden Globes – and she'll find out today whether or not the Academy Awards have followed suit.
Nominations kick off from 5.30am in Los Angeles, which is the more reasonable time of 1.30pm over here!
Jen, however, has insisted she will NOT be watching the nominations read out live, and instead will be cuddled up in bed with her fiancé Justin Theroux and their dogs.
"I'm not going to torture myself!" she told E! News.
Good luck, Jen!
Meanwhile, at last night's premiere, she walked the red carpet without Justin, instead posing alongside handsome co-star Chris Messina.
