Jennifer Lawrence has had to be rescued from a crush of fans clamouring to get her autograph outside a TV studio.
The Hunger Games star had been appearing on The Late Show With David Letterman in the US and stopped to greet fans afterwards.
But according to Us Weekly, when she was led away from the crowds and then ran back to sign more autographs, there was so much excitement that the barrier holding her fans back toppled over.
Minders had to whisk Jen away from the scene before the crowd got out of control.
Earlier on the show, the actress revealed her lack of singing talent when talking about having to perform a song in The Hunger Games: Mockingjay Part 1.
She said: “I do not like singing in front of other people, that’s like my biggest fear. I cried on set that day. I’m scarred from my childhood.
“I have a Southern mother that used to tell me I was amazing at everything and I could do everything, but I can’t. I had this tone-deaf-Amy-Winehouse voice and I sang in front of the school when I was 8, because I thought I could.”
Jennifer said the song she had sung was Have A Holly Jolly Christmas, and gave a rendition of part of it in a growling voice, saying: “My dad laughed for the entire week. I’d hear him around the house, imitating me. I hate it, I hate it!”
David then joined her in singing the Christmas song as they both duetted in a deep voice.
Jennifer added of her Hunger Games song: “It was called The Hanging Tree, which was where I felt like going.”
She said she had wanted Lorde, who sings on the soundtrack, to be dubbed over her scene: “I was like, will you guys please get Lorde and lip-sync it? And they said no, so it’s really me, but I’ve avoided that scene.”
