Would you let Justin Bieber babysit your kids? Well, Kourtney Kardashian and Scott Disick did! The Kardashian krew went out this past weekend for a day of family fun by the pool, and singer Justin Bieber tagged along. Kris Jenner managed to snap a picture of her grandson Mason and Justin splashing around in the pool, having what looks like an awesome time for the little guy. She captioned the pic “Best babysitter ever!” although we’re not too sure of that. Luckily Grandma Kris didn’t stray too far from the scene, as she also got a selfie with The Biebs. So cute!
