Jack Nicholson Jennifer LawrenceIt was a moment that’s sure to live in Oscars infamy.

That awkward moment when Jack Nicholson interrupts your post Academy Awards interview.

Best Actress winner Jennifer Lawrence had just finished describing her big win with “Good Morning America” co-host George Stephanopoulos: “I feel like I can’t even remember. It’s kind of an insane moment and it was just really exciting. It was really just shocking. It was the first time I’ve ever felt, like, actual shock.”

Out of the blue, the 75-year-old Nicholson walked into the interview and said to Lawrence, “You did such a beautiful job. I didn’t mean to cross into your interview but I had to congratulate you.”

“You’re being really rude,” Lawrence, 22, quipped.

After a brief exchange, Nicholson exited.

Lawrence then exclaimed, “Oh my God…Is he still there?”

“I’ll be waiting,” said Nicholson, who popped his head back into the shot.

Lawrence had never met Nicholson before.
