Tristan Thompson has apologised to his ex Khloe Kardashian after a paternity test revealed he fathered a child with Maralee Nichols.

The 30 year old pro basketball player admitted Khloe mother of his 3-year-old daughter True doesn’t deserve the “heartache and humiliation” he has caused her, after it was confirmed he has a son with personal trainer Maralee.

He wrote on his Instagram Stories: “Today, paternity test results reveal that I fathered a child with Maralee Nichols. I take full responsibility for my actions. Now that paternity has been established I look forward to amicably raising our son.

“I sincerely apologise to everyone I’ve hurt or disappointed throughout this ordeal both publicly and privately.

“Khloe, you don’t deserve this. You don’t deserve the heartache and humiliation I have caused you. You don’t deserve the way I have treated you over the years.”

Thompson insisted he has the “utmost respect and love” for Khloe, and said he is “incredibly sorry”.

He added: “My actions certainly have not lined up with the way I view you. I have the utmost respect and love for you. Regardless of what you may think. Again, I am so incredibly sorry.”

Thompson’s paternity test results come after Nichols filed a lawsuit against him for child support, claiming he was her son’s father, following the birth on December 1.
