Kris Jenner Says Justin Bieber Is the ‘Best Babysitter in the World’ Proving Once Again They’re Best Buds

According to Kardashian empress Kris Jenner, Justin Bieber is “the best babysitter in the world.” And no, he wasn’t babysitting 17-year-old Kylie Jenner.

Biebs, 21, and the Kardashians had a pool day yesterday, and it looks like he took great care of one little Mr. Mason Disick (age 5).

He posted this adorable pic of Mason playing on his back, and actually it looks like Bieber is enjoying playing babysitter for a day.

Mason is cool as a fan

Kris reposted the same pic with the caption, “#Mason & @JustinBieber family pool day!!! #bestbabysitterintheworld ❤️ #Repost @justinbieber ・・・Mason is cool as a fan.” 

Biebs and the Kardashians have had close ties for a while now, so it comes as no surprise Kris gave Justin her seal of approval.

Earlier in the week, she posted some pics from Bieber and Kendall’s shoot for Vogue, calling them a “dream team.”

On Justin’s birthday (March 1, 2015), she wished him happy birthday calling him an “amazing young man.”

And then several weeks before that, Jenner praised him for giving her a shirt… um, pair of sunglasses:

See? They’re like, best buds.
