Marcia Cross became a mom on Tuesday, welcoming fraternal twin daughters, her rep confirms to PEOPLE exclusively.

The girls, Eden and Savannah, who were born at a Los Angeles hospital, are the first children for the

Desperate Housewives

actress, 44, and her stockbroker husband Tom Mahoney, 49, who married in June 2006.

"Mother and babies are all doing well," says Cross's rep, Heidi Slan.

Cross had been on bed rest since January.
