Melissa Peterman, who plays the wacky dental hygienist Barbra Jean on the WB show Reba,
and her husband, actor John Brady, became first-time parents Thursday, PEOPLE reports.
The two welcomed their new son into the world Oct. 20 at Cedars-Sinai Medical Center in Los Angeles, a rep for the couple said. The boy, Riley David Brady, weighed in at 8 lbs. 5 oz.
"Mother and baby are doing well and resting at the hospital," the rep said.
Peterman's character is married to Reba's ex-husband on the show. The 35-year-old actress has had roles in several films, including Fargo
and Recipe for Disaster,
as well as on television in Just Shoot Me
and The Pitts.
