One pic showed the pop star shirtless in New York Knicks shorts, while the other has the Biebs, 21, wrapping his arms around the 19-year-old model’s waist.
Jenner also shared a solo photo of her rocking the same bikini top on her Instagram, while her BFF Hailey Baldwin posted a pic of the two girls, writing, "good start to Coachella.” The music festival starts today near Palm Springs.
Bieber has been close with the Kardashian/Jenner family for years. He was recently spotted in Las Vegas with Kourtney Kardashian and her kids, and on Valentine's Day with Kim Kardashian and Kanye West.
Bieber was on the Ryan Seacrest radio show last week and told the host, “I’m single right now and I do enjoy it.”
