Kendall Jenner and Hailey Bieber left their men at home on Monday … and then proceeded to have a helluva girls’ night out at the Lakers game!!

The A-list duo — sans Justin Bieber and Bad Bunny — sat in courtside seats with friends as LeBron James and Co. took on the Oklahoma City Thunder … and it seems there wasn’t one moment where they weren’t enjoying themselves.

Cameras spotted Kendall sippin’ from a custom cup with her 818 tequila logo on it … and later, she and Hailey were seen jokingly flippin’ off a fellow fan.

At one point, they were able to get their hands on a game ball too!

No word on why Justin and Bad Bunny couldn’t make the game — but, clearly, the girls didn’t mind their absence.

Other celebs were at Crypto.com Arena taking in the action as well — Dave Chappelle, Colin Jost and David Duchovny all had great chairs for the contest — and, finally, L.A. was able to treat them to a W.

LeBron scored 25 points, while Anthony Davis logged 27, and the Lakers cruised to a 112-105 victory — their first dub in nearly a week.

Seems the ladies might be a good luck charm for the team — so, see ya’ll back when the Lake Show takes on the Mavericks on Wednesday?!
