Marcia Cross, who is expecting twins in April
, is looking forward to seeing double.
"I won the lottery at my age to have two," the 44-year-old Desperate Housewives
star tells TV's Extra
Cross and stockbroker Tom Mahoney, 48, were married in June
. In October, Cross announced on The Ellen DeGeneres Show
she was expecting twins, saying: "I was sort of blown away that I was having twins, so I just needed a minute to deal with it."
And there are some things she's still dealing with. "I was really freaked out and I was terrified – what if I can't be a good mother to two and somebody would always be feeling left out?" she tells Extra
Unlike her Housewives
character, Bree Van de Kamp, Cross says she's "domestically challenged with a very big heart."
She also clears up any rumors of a problem pregnancy – "I haven't had a thing," she says, "I am absolutely, 100 percent fine" – but admits, "It's hard to carry around all that weight. I wake up feeling like me and then I step on the ground and I'm like, whose body is that walking to the bathroom?"
As for this week's news that her costar, Eva Longoria, is engaged to Tony Parker
, Cross says: "She showed me the ring and I screamed. I think I scared them. Tony was there, and it was just fantastic!"
