William Petersen Welcomes Twins Via Surrogate

Double the congratulations are in order for actor William Petersen!

The CSI alum, 58, and wife Gina Cirone welcomed twins - a boy and a girl - via surrogate on July 5, PEOPLE reports.

The pair were born prematurely, Petersen's rep tells the magazine.

"The babies are doing great and are improving every day and we can't wait for them to come home," the couple, who married in July 2003, says.

Petersen is already dad to 36-year-old daughter Maite who has two young sons of her own.
