Kendall Jenner and boyfriend Devin Booker are Instagram-official

Kendall Jenner and boyfriend Devin Booker took their romance to Instagram.

Jenner, 25, confirmed her romance with the 24-year-old Phoenix Suns player on Valentine’s Day by posting a photo showing Booker cuddling up on her. Smiling from ear-to-ear, Jenner captioned it with a simple white heart emoji.

Booker also got in on the social-media fun, posting a video of Jenner playing with her dog and captioning it with an orange heart. He followed that up with a black-and-white photo of him, Jenner and her dog all snuggling on a towel by the water.

While the couple have never confirmed their romance themselves until Sunday — though they’ve flirted plenty on Instagram — Jenner and Booker have been rumored to be dating since last spring.

They were then spotted out together various times, further fueling the rumors that they were an item. Following Justin Bieber’s star-studded party for Justine Skye in August, spies spotted Jenner and Booker grabbing breakfast together with Booker’s dog, Haven.

This past January, while Jenner was vacationing in Mexico, Booker left a thirsty comment on his girlfriend’s bikini photo.

“Whew,” Booker wrote above the photos, adding a sweating emoji alongside one of the snaps.
