Jen released a statement to Entertainment Weekly, apologizing for her "brain fart" and thanking David O. Russell and Harvey Weinstein.
Jen said: "In the whirlwind of last night, I was remiss to thank two incredibly important people to this film and in my life...I will never be able to forgive myself for such a brain fart but I hope that you both can. Obviously it was not on purpose, I couldn't remember what I had already said and my mind went completely blank--your brain does funny things during the most overwhelming moment of your life!"
We're sure they won't hold it against her! Check out more memorable quotes from Jen backstage in the Oscars press room below:
