Thompson confirmed that he fathered Theo in January 2022, but has not publicly discussed his son with Nichols since.

Thompson conceived Theo with Nichols while he and Kardashian were still together and expecting their son Tatum, who was born in August 2022 via surrogate.

The pair also share 5½-year-old daughter True, and Thompson is father to Prince Oliver, 6½, with ex Jordan Craig.

In a conversation about his decision to talk to different members of Kardashian's family and try to alleviate awkwardness and tension, the NBA player told the Good American founder, 39, that he wanted to be on a path toward making things right.

"In this family, if you do something to one of us, it affects everyone and they're entitled to their feelings. It's not some small thing that happened," she told Thompson on a recent episode of The Kardashians.

"No, I hear you," Thompson replied.

Kardashian acknowledged that "Time has gone by. It's done."

"My son is here, your other son is here and some of their emotions have settled down — not forgotten, not forgiven, any of that — just settled down," she said.
