'Real Housewives Of Orange County' Vicki Gunvalson To Be A Grandmother

Looks as if the "Real Housewives of Orange County" clan is getting a much younger member than originally anticipated: Vicki Gunvalson's daughter is expecting. According to Us Weekly, 24-year-old Briana Wolfsmith is four months pregnant -- and surprised the veteran "Real Houswife" with the news.

"[The pregnancy] was definitely a surprise to Vicki," a source told the publication. "Briana is really happy, and now that Vicki knows, she's really excited too."

Wolfsmith, a nurse, married Ryan Culberson, a U.S. service member who was stationed in Afghanistan, in Las Vegas in October 2011. Meanwhile, mom Vicki recently discussed with HuffPost Celebrity her transition from one of the youngest cast members of "Orange County," now in its seventh season, to one of its oldest.

"They are bringing in the girls 16 years younger. Hello," Vicki said. "I think the producers wanted to sexercise it so we got the younger girls, but it's okay, just more fights."

CORRECTION: As sources are conflicting about the branch of the armed services of which Culberson is a member, a reference to him as a soldier has been edited.
