Sorry, A$AP Rocky — you snooze, you lose! After the rapper and Kendall Jenner finally went public with their relationship back in May at the 2017 Met Gala after a year of dating, things seemed to have fizzled out. Now Kendall is moving on with NBA star Blake Griffin and sources have revealed that they're taking the next step in their relationship.

"Kendall and Blake are definitely dating and hooking up. They are having a good time together," a source revealed to Us Weekly. "It’s a little early to call them boyfriend and girlfriend. Kendall won't settle down soon — she is busy and likes her freedom.”

Last week, Kenny was spotted out on a double date with the Los Angeles Clippers player, her bestie Hailey Baldwin, and Hailey's beau, Memphis Grizzlies player Chandler Parsons. The foursome enjoyed a dinner together at Craig’s in Los Angeles. The following day, Blake, 28, was also spotted out on a solo date with Kendall at the Malibu hotspot Nobu.

While Kendall is out and about with her new beau, A$AP is definitely feeling some type of way about it, and sources revealed to Hollywood Life that the "F–kin' Problems" rapper isn't really handling it well. “A$AP is very aware of Kendall and Blake and it honestly does make him a little jealous,” the insider said.

Even though Kenny seems happy with Blake, it seems like A$AP's unwillingness to commit is the reason why the 21-year-old decided to pursue other options. “He has fun with Kendall but up until now hadn’t really been obsessed with her or anything," the source continued. "He liked seeing her when it was convenient for both of them but didn’t make her his top priority. Looks like it was his loss because Blake is putting in some serious work. He’s into Kendall and making a big move. He definitely wants to be the only guy in her life.”
