After taking home the Oscar for Best Actress for her role in Silver Linings Playbook on Sunday, Jennifer Lawrence got hit on by actor Jack Nicholson.

Lawrence gave a funny acceptance speech for winning Best Actress seconds after tripping on the way to the podium and many thought those would be most memorable moments of her night. But while being interviewed by ABC's George Stephanopoulos backstage, Nicholson walked over to congratulate the actress and told her she looked like someone he used to date.

"Enjoy the night. I loved you in the movie. It was great," Nicholson said before adding, "You look like an old girlfriend of mine."

Lawrence played along and replied, "Oh really? Do I look like a new girlfriend?" 

"I thought about it," Nicholson said. 

Lawrence talked with Stephanopoulous about her huge win and described it as an "insane moment" when Nicholson showed up again and appeared to check out Lawrence's butt, according to  Hollywood Life. 

"Oh, you got a fan here. Oh," said Stephanopoulos as Nicholson came back.

The actor apologized for interrupting and was then jokingly told off by Lawrence.

"Yeah, you're being really rude," she joked as Nicholson complimented her on her win.

"Good to see you. I enjoyed it," he said, to which she replied, "Thank you. I loved all your movies."

Nicholson, 75, was at the Oscars on Sunday to present the award for Best Film with Michelle Obama. Lawrence, 22, is the same age as Nicholson's daughter Lorraine.

The Oscar-winning actress was seen leaving a hair salon in Beverly Hills on Monday sporting near jet black hair, according to the Daily Mail. She changed her hair color to get into her Hunger Games character, Katniss Everdeen. Lawrence is expected to work on re-shoots for the film in Hawaii as soon as this week.
