Powerhouse attorney Gloria Allred tells Radar that she's "not surprised" to hear he was allegedly caught sneaking into a bedroom with three women over the weekend.
Sources claim Tristan arrived at the birthday party for Drake's bodyguard and headed straight to the bar for tequila shots. Witnesses allege he disappeared into a bedroom with three women and reappeared 30 minutes later looking "disheveled."
Another eyewitness claims Tristan was seen grabbing another woman's butt at the party.
“He was having a blast - he was actually laughing and simultaneously taking shots and drinking straight out of a bottle of champagne," said one partygoer.
Hours after the news broke, Page Six reported it's over for Khloé and Tristan.
According to the outlet, the Keeping Up With The Kardashians star ended their relationship weeks ago. However, the two were seen looking pretty cozy at lunch together with True just days ago.
"They’re getting along. There is no drama. Everything is amicable and they are on the same page with co-parenting," the insider said.
As for Gloria, she says her original offer to Tristan regarding a sitdown with Sydney still stands.
Last month, the Los Angeles-based attorney told Radar she'd be willing to "share evidence" given to her by Sydney regarding her alleged relationship with Tristan "provided that Mr. Thompson will make himself available in person to answer my questions and provide us with documents that we request."
Gloria challenged Tristan after he denied the hookup with Sydney took place.
"If Mr. Thompson has nothing to hide, then we would expect that he will make himself available for questioning by me and that he will voluntarily provide the documents," her statement read.
She even extended the invite to Khloé.
"Khloe Kardashian is welcome to attend. We believe that the truth will emerge through this process. When we conclude our investigation, we will then advise Sydney regarding her legal options," Gloria stated.
Tristan and Khloé have kept quiet regarding the latest cheating allegations, but the NBA player doesn't seem to be sweating it.
He was spotted leaving the popular nightclub Nightingale in L.A. in the wee hours of Monday morning. Tristan wasn't trying to hide either, sporting a bright yellow sweatsuit.
