Tristan Thompson is finally breaking his silence about what he recalls going down with Maralee Nichols.

He reportedly got Nichols pregnant in March on his birthday while he and Khloe were still together.

She filed a paternity lawsuit against Thompson, and claimed in legal documents that their relationship took place over the course of five months.

Thompson initially said the ONLY time he was with the personal trainer was during a 24-hour period in March where they had sex several times in a hotel.

New legal documents have been released, and they reveal how Thompson and Nichols arranged to meet up.

"We saw each other sporadically between December 2020 and March 13, 2021 and did not have sexual intercourse in California during that time,” the NBA player claims in the documents.

“From December 2020 through March 2021, we saw other on such a basis. We never had any telephone calls, emails, nor did we exchange text messages. We only communicated via the Snapchat application,” he added.

“I only recall that Petitioner and I had sexual relations in March of 2021 and at no other time in 2021.”

“I am certain that if the child is deemed to be my child that the only date of conception was March 13, 2021, because it was my birthday. As I stated, our relationship was based on sex.”
