Addressing his ex, Khloé Kardashian, the basketball player apologized, writing, “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. My actions have certainly not lined up with the way I view you.”

He continued, “I have the utmost respect and love for you. Regardless of what you may think. Again, I am so incredibly sorry.”

Nichols recently sued Thompson for child support, claiming he had offered her $75,000 to keep quiet about the baby, who was born last month.

Thompson has two other children. A son, Prince, with ex Jordan Craig, and a daughter, True, with Kardashian.

Kardashian’s ex-husband, Lamar Odom, then commented on the Thompson news in a Facebook post discussing the results of the paternity test.

According to E! News, Odom, who was married to Kardashian from 2009 to 2016, wrote: “I truly wish nothing but the best for her and I’m hoping we can reconnect and talk one day as friends. She is a good person and deserves the world.”

Nichols’ public relations consultant Harvey Englander has since told ET Canada in a statement: “There was never any doubt that Tristan Thompson was the father of Maralee Nichols’ baby.

“Tristan made numerous false and defamatory statements and declarations about Maralee over the past few months, and she is taking his contrite statement today in the context of all of those statements.”
