Andy Cohen is expecting his first child soon, so Backstreet Boys decided to surprise the Watch What Happens Live host by singing his unborn son a lullaby.
“We have a very special treat just for your future baby boy,” AJ McLean says in the video below. “So this is from us to you.”
The pop band then sings “Twinkle Twinkle Little Star” a cappella, complete with perfect harmonies. McLean then joked that they should put out a children’s album — although it does sound like a great idea.
Check out the video below, and try not to be lulled to sleep.
