According to E! News, Jenner and Griffin enjoyed a "double date" with the reality star's pal, Hailey Baldwin, and Griffin's fellow basketball player, Chandler Parsons, before heading out to party at Nightingale Plaza with a small group of friends. The outlet's source says the couple arrived and left the club together.
Jenner was last linked to A$AP Rocky, and though they haven't been spotted together in some time, People reports that the two are still dating.
"Kendall is keeping her options open," People's source says. "She's still dating A$AP Rocky as well, but she and Blake are hanging out, and there's potential there."
