Dennis & Kimberly Quaid Welcome a Boy & Girl
Thomas Boone was born at 8:26 a.m. and weighed 6 lb. 12 oz., while Zoe Grace came two minutes later and weighed 5 lb. 9 oz.
In a statement, the Quaids said, "God has definitely blessed us."
The twins were born via a gestational carrier – a woman who carries another couple's baby conceived by the parents' own egg and sperm.
After the pregnancy was announced in May, Quaid, 53, told PEOPLE, "We are both so thrilled and excited. This is something we've wanted for some time."
The twins are Quaid's second and third children. He also has a 15-year-old son, Jack Henry, with ex-wife Meg Ryan.
