The “Watch What Happens Live” host was surprised with a clip from the boy band where they sang an a cappella rendition of “Twinkle, Twinkle Little Star”.

AJ McLean starts the clip by saying, “Andy, on behalf of myself and the fellas, we have a very special treat just for your future baby boy. So this is from us to you.”

The group, which also includes Nick Carter, Kevin Richardson, Brian Littrell, and Howie Dorough, then harmonize the lullaby in perfect tune.

Littrell jokes that he “almost fell asleep” while McLean notes that they should make a kids album.
