Justin Bieber took a dip with the cutest swimming buddy – Mason Disick.

The newly reformed pop star shared an adorable snap with Kourtney Kardashian‘s oldest child Mason Disick on Instagram, Friday.

In the photo Disick playfully rides on the 21-year-old’s back in a crowded pool. The “Baby” singer captioned the photo, “Mason is as cool as a fan.”

Kardashian, 35, who is also mother to Penelope, 2, and Reign, 3 months, with boyfriend Scott Disick, re-shared the playdate photo via her Instagram account, as well.

Bieber has been mingling with the Kardashian-Jenner clan a lot as of late. He was recently photographed with Kendall Jenner by Mario Testino for the April issue of Vogue. Almost shirtless, Bieber sips a drink with his arm around a beaming, bikini-clad Jenner in one of the pics by the famed photographer. The two were also joined by Ansel Elgort and GiGi Hadid (who is Jenner’s real-life BFF) for the spread.

The star of an upcoming Comedy Central roast also shared a poolside pic earlier on Friday of a beautiful woman feeding him grapes as he lounged shirtless, writing “The kids gotta eat too.”
