Jennifer Lawrence was in the middle of an interview with George Stephanopoulos when Jack Nicholson decided he'd like to join in on the fun. Nicholson told Stephanopoulos to save the politics for later and then introduced himself to Lawrence, congratulating her on her Oscar. Before leaving he says she looks like one of his old girlfriends. She quips back with, "Really? Do I look like a new girlfriend?"
"I thought about it." - Jack Nicholson.
Lawrence seems genuinely giddy about the whole interaction as Nicholson put on his signature shades and creeped over her shoulder and added an, "I'll be waiting" before moving on.
