During a backstage interview following the Academy Awards on Sunday night, "Best Actress" winner Jennifer Lawrence was left speechless after a flirty exchange with Jack Nicholson.

The actress, 22, was being interviewed by George Stephanopoulos for a segment for "Good Morning America" when Nicholson, 75, interrupted her from behind, saying: "You did such a beautiful job (in the movie). I don't mean to crash your interview..."

Lawrence then joked, "Yeah, you're being really rude!"
 
Nicholson then commented how she bore a striking resemblance to an old flame of his, prompting her to respond, "Oh really? Do I look like a new girlfriend?"

Lawrence, who is currently single, laughed as the actor quipped: "I thought about it!" but Lawrence was soon regretting her risque behaviour as she gasped, "Oh my God" and buried her head in her hands as Nicholson walked away.
