Gunvalson announced the news on her Facebook, writing, "News everyone has been waiting for: Troy William Culberson was born a healthy 7 lbs, 11 ounces and 20 inches at 7:53 a.m. this morning! Thank you everyone for all your support! I'm a GRANDMA! Im so proud of Briana and Ryan. They will make amazing parents."

It's a happy moment for the family, since Briana had a "high-risk pregnancy," according to a source who opened up to E! News. There were a few complications before the birth, the source says. "The baby's heart started dropping [Thursday]...She was in labor for like 30 hours!"

Little Troy is the first child for 24-year-old Briana and her husband, Ryan Culberson, and the first grandchild for 50-year-old Vicki.
