Three months after having twins, Marcia Cross has almost hit her post-birth target weight, she says.
“I’m still working on it, but it’s happening a lot faster than I expected,” Cross, 45, told PEOPLE at Thursday’s BlackBerry Curve launch party in Los Angeles.
The actress, who welcomed daughters Eden and Savannah in February, has been working out at home with exercise DVD’s and at L.A. gym Burn 60.
“I think it’s the end of those last few pounds, I hope,” she said. “It probably won’t happen until I stop breastfeeding!”
Meanwhile, she’s still enjoying new motherhood. “I’m so happy. Sometimes very tired, but mostly just a happy mother,” she said. “I like to get [the babies] out now, just go out and show them the world. Say hi to the flowers.”
Cross said her husband of 11 months, Tom Mahoney, has been a huge help: “He’s there every minute, and he’s as madly in love with them as I am. I don’t know what I would do if I had one of those husbands who was just not interested.”
As for whether they’ll stamp their passports for her Desperate Housewives costar Eva Longoria’s Paris wedding in July, Cross says she hasn’t decided – she hasn’t traveled with the twins yet.
“We’re going to go on a trial trip this weekend and see how it goes,” she said. “We have no idea what it’s going to be like traveling, so we’ll have to figure it out.”
