HOLLYWOOD, Calif. — Rebecca Romijn and Jerry O'Connell have welcomed twin baby girls, according to People.

The couple's first children, Dolly Rebecca Rose (Romijn is a huge Dolly Parton fan) and Charlie Tamara Tulip, were born on Dec. 28, the magazine says.

"Mother, father and both girls are all home and doing well," a rep for the actress told the mag.

Romijn, 36, and O'Connell, 34, started dating in 2004 and married last July on their ranch in Calabasas, Calif. They have both been outspoken about starting a family, with Romijn telling Self magazine in August: "Hopefully, I'll have children, if I'm lucky enough."

While they are first-time parents, plenty of help is on the way for the pair.

"My mom's coming to help us as much as we need," the "Ugly Betty" star previously told People. "But this is something we're really looking forward to."

"I'm really excited to see what happens next and to visit a completely different chapter in my life." she added.
