Jennifer Lawrence looked like a ''freak'' in front of Jennifer Lopez.

The 23-year-old beauty has revealed how she was left dancing alone in front of the 'American Idol' judge at a recent charity party after she and 'Tonight Show' host Jimmy Fallon hatched a plan to get Jennifer to dance with them.

The 'X-Men: Days of Future Past' star recalled the embarrassing moment while appearing on Jimmy's talk show last night (15.05.14), explaining: ''We came up with this plan together. We're dancing, we see J.Lo, and we're like, 'We've got to ask J.Lo to dance!' And I was like, we'll do a spin and then we'll go, 'Dance with us' [to J.Lo].

''Basically, I do it, and then I look and he's gone! It's just me looking at J.Lo, going, 'Dance with... me?' And she was just looking at me. You made me look like a freak in front of J.Lo!''

Good-humoured Jennifer had Jimmy, 39, and the audience in hysterics as she sported a beard - matching her blonde locks - while taking the stage for her interview.

The Oscar winner quipped: ''I couldn't help it! Everybody's talking about how Jennifer Lawrence is growing her hair out a little bit, so I decided to grow my chin out a little bit.''
