Oscar-winning actress Jennifer Lawrence has said that her favourite moment of 2015 was when she and her friend Amy Schumer got drunk and danced on music star Billy Joel's piano.

"Amy is, like, the s**t. We got so drunk we ended up on top of Billy Joel's piano. That was really cool... She didn't have to share that piano with me and she did," Lawrence told etonline.com.

Meanwhile, Lawrence also said that it's time to "move on" from the "Hunger Games" franchise, which helped establish her as one of Hollywood's most in-demand actresses.

"It's crazy. I signed on to these projects when I was 20 years old. I remember being like, 'Oh my God, I'm going to be 25 when I'm finished. It seemed so far away. It does feel over. It didn't for a while and I didn't think it would ever sink in, but it has now. It feels over. And that's okay. It's okay to move on," she said.
