The General Hospital actor confirmed he and wife Sheree Burton have ended their relationship. 

In an Instagram Story on May 4, he wrote, "I wanted to clear something up. Sheree and I are separated."

He also alleged that while Sheree is pregnant, 

the baby is not his. "She recently announced that she's expecting her 4th child," he wrote. 

"The child is not mine." It's unclear if Sheree has a new partner.

Steve and Sheree married in 1999 and share children Makena, 18, Jack, 16, and Brooklyn, 7.

"We are still co-parenting our three beautiful kids," 

he said in his post, adding, "We would appreciate privacy at this time. Much luv, Steve."

Sheree, who describes herself as a nutrition and fitness coach, has not publicly commented on Steve's announcement. 

News has reached out to her for comment but has not heard back.
