Tristan Thompson is reportedly expecting a third child, this time with his personal trainer in Houston.

Maralee Nichols is suing Thompson seeking support for the child, despite the fact that her child has not yet been born, according to the Daily Mail citing court documents. The baby was allegedly conceived on Thompson's 30th birthday in March, when he and Khloé Kardashian were still in a relationship.

Thompson admitted to having gone with Nichols several times to a hotel after the pair attended a party together, according to a statement included in the dossier. However, Thompson claims that night was the only time he had intercourse with Nichols, but Nichols's lawyers claim that their relationship began at least 5 months before his 30th birthday.

Thompson has a daughter with Khloe Kardashian, True, and a 4-year-old son, Prince Thompson, with former model Jordan Craig.

The separation of Khloe and Tristan also came after reports that he was suspected of being seen entering a room with three women at a Bel-Air birthday party and came out 30 minutes later and looked "messy". This happened just one day after he had dined with Khloe and True.
