The Quaids got the twins.
Dennis Quaid and his wife, Kimberly, welcomed Thomas Boone and Zoe Grace on Thursday in Santa Monica, California, the actor's publicist, Cara Tripicchio, said Monday.
The couple are the biological parents of the twins, who were born to a surrogate mother. Thomas weighed 6 pounds, 12 ounces (about 3 kilos); his sister weighed 5 pounds, 9 ounces (2.5 kilograms), Tripicchio said.
"God has definitely blessed us," the couple said in a statement.
Quaid, 53, has a 15-year-old son, Jack Henry Quaid, from his marriage to Meg Ryan.
His screen credits include "Far From Heaven," "The Rookie," "The Right Stuff," "Great Balls of Fire!" and "The Parent Trap."
Quaid and Kimberly Buffington were married in 2004.
