Christy Turlington Burns has a new gig.

The model and philanthropist has become the new face of Apple Watch, the highly anticipated smart watch the company announced today.

Apple tapped the supermodel to try out the Apple Watch. During their announcement, the company showed video of her running a half marathon wearing the watch.

Burns made an appearance during Apple’s live streamed event, walking on stage to banter with CEO Tim Cook. She said she will try to beat her four-hour record in the upcoming London Marathon.

"Apple Watch is going to help me get there," she said.
