Watch Nick Jonas sing a medley of songs, including One Direction's What Makes You Beautiful.
How did Nick do with the 1D hit?
Aside from the sing-along that sort of drowns out his performance, we'd say he's right on the money.
In fact, we'd love to see the Jonas Brothers do a cover of What Makes You Beautiful! How great would that be?
Nick gave his fans the gift of song in between shows for the musical How to Succeed in Business Without Really Trying last Saturday, playing Jonas Brothers' Love Bug and the 1D classic, as well as a little Bruno Mars.
He tweeted: "Did an acoustic set outside the theatre in-between shows today. #bestfansintheworld"
