A paternity test confirmed that Tristan Thompson is the father of a third child. He had a boy with a Texas woman, Maralee Nichols, who recently sued him for child support.

Thompson was apparently still dating Khloe Kardashian, with whom he shares daughter True, when he became pregnant with the baby. On January 3, the basketball player issued an apology on Instagram Stories

. 'I take full responsibility for my actions. Now that the paternity relationship is established, I look forward to raising our son amicably."

"I sincerely apologize to everyone I have hurt or disappointed publicly or privately throughout this ordeal."

On the second slide, Thompson referred to Kardashian. 'Khloe, you don't deserve this,' he wrote. 'You do not deserve the heartache and humiliation I have caused you. You do not deserve the way I have treated you over the years. My actions are certainly not consistent with the way I see you. I have the utmost respect and affection for you. Regardless of what you may think. Again, I am truly sorry."

Thompson's relationship with Kardashian has been on and off for years as he has been embroiled in cheating scandal after cheating scandal. The founder of Good American reportedly believed he would change and gave him new chances on numerous occasions. However, their relationship these days seems to be limited to co-parenting 3-year-old True. Thompson also has a 5-year-old son, Prince, with ex Jordan Craig.
