Tristan Thompson's alleged mistress — Instagram model Lani Blair — didn't show up to her waitressing shift at Club Angels strip club in Queens, New York last night amid the cheating scandal, Breaking Celebrity News can exclusively report.

Blair was expected to arrive at 1 am, but flaked on the gig last minute, a coworker told Breaking Celebrity News.

"After everything she's dealt with today, she's not coming in tonight," the employee said.

According to another server at the club, Blair has worked at the strip club for about six months, and has become close friends with many of the dancers.

Further demonstrating how brazen Thompson's bad behavior became, a bartender at the jiggle joint claimed pregnant Khloe Kardashian's baby daddy frequents the club when he's in New York.

"He shows up here from time to time," the bartender alleged.

As Breaking Celebrity News previously reported, NBA player Thompson, 27, was caught on camera kissing a woman believed to be Blair last weekend at club PH-D in New York.

In Breaking Celebrity News's exclusive photos, he can be seen cozying up to her.

Later that night, he was spotted walking into a swanky hotel with who appeared to be the same woman.

Meanwhile, Kardashian, 33, is expecting her first child any day now while nesting in Thompson's home base of Cleveland, Ohio.

Blair has not responded to Breaking Celebrity News's request for comment, and made all of her social media accounts private in the aftermath of the scandal.
