Entertainment TV Tristan Thompson Admits to Months-Long Sexual Relationship with Woman Who Claims He Fathered Child Maralee Nichols is suing Tristan Thompson for child support and pregnancy-related fees, alleging that he is the father of her baby born earlier this month By Ally Mauch Published on December 15, 2021 12:34 PM Share Tweet Pin Email Tristan Thompson admitted to having a "sporadic," ongoing sexual relationship with Maralee Nichols, the woman who is suing him for child support and pregnancy-related fees after she said they conceived a child together. In a court document filed earlier this month and published by the Daily Mail, the NBA star — who has disputed the paternity of the child, born Dec. 1 — recalled meeting Nichols in late November or early December 2020 at someone's home. At the time, he said he "was very cautious" and "did not foresee that she and I could have any type of relationship." He also denied having sex with her in California around that time, claiming that the "only" possible date of conception for the child is March 13, 2021, Thompson's birthday. Nichols has said the child was conceived in April, per the document. For more on Tristan Thompson and other top stories, listen below to our daily podcast on PEOPLE Every Day.

Abbie Parr/Getty Khloé Kardashian Believed Tristan Thompson 'Would Change' Before He Allegedly Fathered 3rd Child "We did not have a serious ongoing relationship. We saw each other sporadically between December 2020 and March 13, 2021," he wrote. "[Nichols] told me that she had been involved with other athletes and understood the limitations of our relationship; to wit, that we might see each other on a sporadic basis for consensual sex only." "We did not have any dates in the traditional sense at any time; there were no dining at restaurants, going to movies, traveling or any other indicia of a normalized relationship," he later added. "There was only Snapchats of 'where' and 'what time' we would hook up and what hotels would be used." Thompson denied sending the Snapchat messages between him and Nichols that have been made public via other court documents, claiming that they were fabricated. He also said they only communicated via the Snapchat application and that they never "exchange[d] text messages." One of the alleged messages Nichols referenced in her filings said he would soon be retiring from his NBA career and thus be unable to pay ample support, while another allegedly suggested Nichols get an abortion. During the time that Thompson admits to having a sexual relationship with Nichols, he was publicly dating Khloé Kardashian, with whom he shares 3-year-old daughter True.
