Nia Long and Ime Udoka are done.

A source exclusively confirms to PEOPLE magazine that Long, 51, and Udoka, 45, have ended their 13-year-relationship after the former Boston Celtics head coach allegedly had an affair with a female subordinate within the team’s organization.

“The situation is unfortunate and painful, but Nia is focusing on her children and rebuilding her life,” the source says.

A rep for Long also confirms the couple are “no longer together but remain fully committed to co-parenting their son [Kez].”

The couple’s split comes after the Boston Celtics held a press conference in September to address Udoka’s suspension.

“I think the most heartbreaking thing about all of this was seeing my son’s face when the Boston Celtics organization decided to make a very private situation public,” Long told The Hollywood Reporter last week.

In September, just weeks before the start of the 2022-23 NBA season, the Boston Celtics issued a statement on Udoka’s immediate suspension from the team. At the time, they said Udoka had violated “team policies,” and noted his future with the team will be evaluated.
