Married to Jerry O'Connell since 2007 and mom to twin daughters Dolly and Charlie, 4, Romijn said she is constantly amazed by her daughters -- and glad they get on so well.
"I am done having kids," Romijn, 41, said. "Two was always the goal, and we got that and here we are."
Fortunately, Dolly and Charlie entertain themselves.
"They are very good friends," Romijn said. "They are each other's best playdates."
"They keep each other such great company and they play so well but they also fight and it turns on a dime, she said. "I'm constantly admiring them and then breaking up fights but they are each other's best company."
As for her old life with Stamos, Romijn said she doesn't keep in touch with her ex, to whom she was married from 1998 to 2005.
"I have no idea what is going on with him these days," she said.
