The 21-year-old singer shared a photo of himself cuddling up to the 19-year-old reality star on Instagram. Bieber and Jenner enjoyed time with each other and puppy Esther, whom the pop star introduced in March.
Jenner also took to the photo sharing site to post a picture of herself showing off her backside at the hangout session. The model alluded to her friendship with Bieber shortly after on Twitter, writing, "BFFs!" and "fo eva evaaa."
Bieber and Jenner are close friends and often romantically linked in the press. The singer was in an on-and-off relationship with Selena Gomez for several years, and subsequently rumored to be dating Hailey Baldwin. The 18-year-old model denied she and Bieber are together in February.
