Kendall Jenner 'Hit It Off' with Blake Griffin but Is 'Still Talking' to A$AP Rocky: Source

Kendall Jenner is keeping her options open.

In the last month, the supermodel and Keeping Up with the Kardashians star has been spotted several times with Los Angeles Clippers player Blake Griffin — but according to a source, she’s still in touch with rapper A$AP Rocky, with whom she’s been fueling romance rumors since last year.

“Kendall and Blake have been hanging out quite a bit and are having a good time,” a source tells PEOPLE. “They met in passing a few times and hit it off.”

“She’s still talking to Rocky as well,” the insider adds. “But he isn’t the type to settle down or be a good boyfriend, so she’s playing the field too.”

Last week, Jenner, 21, and Griffin, 28, stepped out together in Los Angeles three nights in a row. Of the budding romance, a source previously told PEOPLE that the two are having fun together, but it’s still very casual.

“She’s seeing Blake romantically,” the source said of the NBA star, who shares two children with Brynn Cameron, a former basketball player at USC.

“It’s nothing serious,” the source added. “She has been in L.A. a lot lately and is having fun. Work will soon take over her life again, so who knows what will happen will Blake then. She’s having fun right now and that’s all that matters to her. She takes her career very seriously, and that’s her number one priority right now.”

As for A$AP Rocky? Things do seem to have cooled off since earlier this summer.

In June, a source close to Jenner and the 28-year-old rapper told PEOPLE they’re “definitely still hanging out and are progressively getting more serious.”

“It’s hard for Kendall to settle down still because her schedule is so crazy and she’s always traveling,” the source added. “But she’s as ‘settled’ as she can possibly be at this point with A$AP.”
