Jennifer Lawrence never feels guilty about cutting people out of her life.

She told Entertainment Weekly magazine: "I have a very small circle.

"The moment I feel like someone is using me or is in it for the wrong reasons, I have zero guilt about just cutting them the f**k out of my life."

The 25-year-old beauty thinks she has a "phenomenal bulls**t detector".

She added: "None of my friends bulls**t me. Everything in my life has to be real."

One of the people the 'American Hustle' star counts as a friend is Amy Schumer, and her favourite moment of this year was when she and the 'Trainwreck' actress got drunk and danced on the piano of music star Billy Joel.

She said: "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."

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

She said: "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."
