Briana Wolfsmith, Vicki Gunvalson


Vicki Gunvalson is now a grandmother!

The Real Housewives of Orange County star's daughter, Briana Wolfsmith Culberson, welcomed a baby boy on Friday, Gunvalson's rep confirms to E! News.

According to Vicki's Facebook page, "Troy William Culberson was born a healthy 7 pounds, 11 ounces and [was] 20 inches." A source tells E! News Briana had "a high-risk pregnancy, and the baby's heart started dropping [Thursday]...She was in labor for like 30 hours!"

This is the first child for 24-year-old Briana and her husband, Ryan Culberson, a U.S. soldier.

This is also 50-year-old Vicki's first grandchild.

Congratulations all around!
