A publicist says the couple welcomed a baby boy Tuesday in Florida. They named their new son Benjamin.
The eight-pound, three-ounce boy was born at an undisclosed Florida hospital.
Spokeswoman Samantha Mast said in a statement late Tuesday that the couple and their daughter, Ella Bleu, "are ecstatic and very happy about the newest member of the family." The statement says Preston and baby Benjamin "are healthy and doing beautifully."
This is the third child for Travolta and Preston, who were married in 1991. Their eldest child, son Jett, died last year at age 16.
