Us Weekly has learned that Romijn, 35, and O’Connell, 34, are expecting twins this winter.

A spokesman for the couple confirmed the news Monday morning.

The babies will be the first children for the pair.

Romijn and O’Connell met at a party in 2004; he proposed a year later. They got married in an intimate ceremony in Los Angeles in July 2007. See their wedding photo.

A source close to the actor tells, “Jerry couldn’t be happier about becoming a dad.”

Earlier this month, O’Connell told the magazine that they had been trying to have kids.

“It would be amazing if it happened,” he said at the Much Love Animal Rescue’s “Bow Wow WOW!” event in L.A. July 19. “I hope it does happen.”

He joked that the conception process had been “a lot fun for me,” adding that they go at it “at least a few days a month!”
