Tristan Thompson apologizes to Khloé Kardashian after paternity test confirms he fathered Maralee Nichols’ son

The ex-boyfriend of Khloé Kardashian – with whom he shares a daughter – was taken to court to prove paternity of a baby boy he allegedly fathered with a woman he met while he and Kardashian were an item.

The results are now in, and it turns out Thompson, 30, is indeed the father of fitness maven Maralee Nichols’ child.

"I take full responsibility for my actions," Thompson wrote in a scribe shared to his Instagram Stories on Monday. "Now that paternity has been established, I look forward to amicably raising our son. I sincerely apologize to everyone I've hurt or disappointed throughout this ordeal both publicly and privately."
