Tristan Thompson Calls Sydney Chase A Liar, Sends Cease And Desist

Tristan Thompson is calling BS on claims he slept with Instagram model Sydney Chase.

The Boston Celtics player has hired a lawyer to shoot down allegations from the Instagram model, whom he calls a liar, and is threatening to sue if she keeps yapping. The Celtics star — who’s back in with Khloe Kardashian now — had his attorney, Marty Singer, fire off a cease and desist letter to Chase.

Cheating Allegations

As previously reported Chase appeared on the “No Jumper” podcast and claimed to have had a sexual encounter with Thompson in January. She also called his uncircumcised penis a “peek-a-boo d*ck” and said it was good.

A few days later she went on Tik Tok and doubled down on her claims. She also told The Daily Mail she has receipts in the form of salacious texts from Tristan.

Tristan Calls Her A Liar

In the cease-and desist letter, obtained by TMZ, Singer calls her allegations “malicious defamatory fabrications,” adding, “Mr. Thompson had no relationship with you whatsoever and he never sent you any such texts.”

Singer goes on to accuse Chase of making up quotes from Tristan and having no proof to back up her claims, and blasts her by saying, “It is obvious that you are a liar.”

The letter concludes by saying if Chase doesn’t stop “defaming” Thompson in the media or online, “you do so at your peril since you may find yourself in court attempting to defend your indefensible misconduct.”

No Jumper Responds

Singer also sent a letter to Adam John Grandmaison, host of the “No Jumper” podcast, demanding he take down the interview.

“Yeah, we got a cease-and-desist and deleted it,” Grandmaison told Page Six. “Honestly, I wouldn’t have posted it in the first place if I knew it was going to mess up a relationship.”

“No Jumper” since has reuploaded the video but edited out the portion in which Chase makes her claims about Thompson.”

Chase Claps Back … Again!

Meanwhile, Chase has responded after initially claiming she never received the cease and desist letter.

“I finally received the cease & desist hours after I made my post online,” she wrote on her Instagram Story. “It was first sent to an email I no longer use. However, I’m moving forward with the truth & am choosing not to comply.

“I will not be called a liar,” she concluded.

A few days earlier she also claimed that Khloe reached out to her in her DM’s and wanted to talk. She shared screenshots allegedly sent by the “Keeping Up With the Kardashians” star that begin, “Hey Sydney, this is Khloé…”

In a follow-up message, Khloé allegedly wrote, “I would appreciate if our conversation can remain confidential [prayer hands emoji].”

Well that didn’t happen. She also claimed Tristan reached out to her in April after his daughter True’s birthday party. Meanwhile Khloe hasn’t addressed the allegations, she has also reportedly stopped wearing the massive diamond ring Tristan bought her.
