The Hunger Games star, 24, made dozens of sick children smile when she paid them a visit at the Kosair Children’s Hospital on Christmas Eve.

Photos on Twitter show her posing with the kids by their beds as well as in a group where she was also joined by staff. (And joked about her awkward pose in a video, below.)

Lawrence is no stranger to helping children: she used to serve as an assistant nurse at a children’s summer day camp that her parents ran.

“It’s impossible to shock me or gross me out,” she told the Los Angeles Times.

This wasn’t Lawrence’s first holiday visit to this hospital. The Oscar winner also stopped by last year.

“Thank you for visiting the kids yesterday. We know it meant a lot to them and brightened their day,” the hospital tweeted after that visit.
