Sacramento Kings center Tristan Thompson might be getting a surprise birthday present … nine months late. Maralee Nichols is nine months pregnant and claims that Thompson is the father of her unborn baby boy. She is now suing Thompson for child support. This is all according to the Daily Mail, who broke the news Friday morning.

Nichols says that she conceived the baby when Thompson was in her hometown of Houston in March. The Kings were in Houston for their game against the Rockets on March 11. She says that they had sexual intercourse after attending a party and celebrating Thompson's 30th birthday. Thompson turned 30 on March 13.

Daily Mail states that Thompson did admit to having sexual intercourse with Nichols in his Houston hotel room back in March. Nichols' lawyers claim that the two began seeing each other months before their time in Houston. They also claim that the relationship continued afterwards. According to Thompson, this occurrence was the only time he was intimate with Nichols.

To make things even more confusing, this is all while the Kings big man was in a relationship with ex-girlfriend Khloe Kardashian. This isn't the first time Thompson has been accused of cheating on the reality TV star and mother of his second child, so it isn't too surprising to hear about the possible infidelity. However, Thompson still cares about the mother of his child, recently getting a fan kicked out of a game for talking about Kardashian.

Thompson currently has two children. His ex-girlfriend Jordan Craig gave birth to their son, Prince Thompson, in December 2016. The NBA player agreed to large child care costs to support his son. His daughter with Khloe Kardashian, True Thompson, is a 3-year-old. If Thompson is the father of Nichols' baby boy, he will be a father of three.
