Meet Rebecca Romijn’s Twin Daughters

Inside InStyle's June Sexy issue (on stands May 22), cover girl Rebecca Romijn poses with twins Dolly Rebecca Rose and Charlie Tamara Tulip. Says the actress of her daughters' exclusive debut, "What girls wouldn't want to be featured in InStyle? We figured they would be happy with this choice in 18 years."

"I feel as sexy as I have ever felt," she continues. "I'm a jeans size up from where I usually am, but there's nothing about it that freaks me out -- I've always said that sexy is having a really strong sense of yourself and never taking yourself too seriously."

Romijn also notes that husband Jerry O'Connell has far exceeded her expectations as a father: "He's got endless amounts of energy, and he's having such a blast with these girls." She jokes that he will be a strict father: "He's determined not to let them ever date while he is alive."

Rebecca is eager to pass her style sense on to her daughters. "I know they're going to have a lot to say by the time they turn 2, so until then I get to dress them however I want." The actress' current child style icon? Madonna's daughter Lourdes: "She's doing new wave postmodern Punky Brewster geek chic. She's one to watch."

Of course, Romijn is more focused on looking at her own girls. "Being a mom makes me feel whole and like I understand the meaning of life," she says. "All I want to do is stare into my babies' eyes nonstop!"
