Candice Crawford and Tony Romo welcome another son

Actor Chace Crawford has become an uncle again after his sister Candice welcomed her third son with retired football star Tony Romo.

The former Dallas Cowboys quarterback announced the news of his family's new arrival on Twitter on Wednesday (23Aug17).

"Welcomed our third boy Jones McCoy Romo into the world today!," the proud dad declared alongside a photo of the newborn. "Ten fingers and ten toes. All healthy. Almost have my basketball team built."

Tony and his wife Candice Crawford, who wed in 2011, are also parents to Rivers, three, and five-year-old Hawkins.

The sportsman, who previously dated Jessica Simpson, will have plenty of time to spend with his growing family - he hung up his Dallas Cowboys jersey in April (17), and has since become a TV analyst.
