The football star and basketball player welcome Cole Cameron Leinart

Arizona Cardinals quarterback Matt Leinart and University of Southern California basketball player Brynn Cameron welcomed a son on Tuesday, PEOPLE has learned.

Cole Cameron Leinart was born at 9:33 p.m. in California, and weighed in at 6 lbs., 7 oz.

“The baby is healthy, and both families are very excited,” a source tells PEOPLE. “Matt is thrilled.”

Leinart, who was present for his son’s birth, had to rush to the hospital from his late afternoon practice. One of PEOPLE’s 2006 Most Beautiful People, the football star, 23, graduated from USC in December 2005 and lives in Los Angeles and Arizona.

Cameron, who is a junior at USC, will sit out the 2006-07 basketball season.

“It’s an exciting time in their life,” a source who knows both athletes told PEOPLE in August when the two announced they were expecting. “They both have support from their families.”

Leinart, a Heisman trophy winner and close pal of Nick Lachey, was linked romantically to Paris Hilton in the past.

Through his Matt Leinart Foundation, the football star helps raise money for underprivileged and disabled children. “Kids are important to Matt,” his rep told PEOPLE in August.
