Real Housewives of Orange County star Vicki Gunvalson is full of surprises this week on Twitter, as she announces that her daughter Briana Wolfsmith-Culberson is not only pregnant with her second child but is having another boy! Hooray!

Briana  who is Vicki's 26-year-old daughter with first husband Michael Wolfsmith  is married to Ryan Culberson. Last season on RHOC, we saw Briana and Ryan welcome their first son, Troy. Now, their brood is about to expand yet again.

Vicki, ever the proud grandmother, took to Twitter on January 9 to announce the happy news.

"So excited!" Vicki writes. "Just found out baby #2 is a BOY! #troybigbrother, #bestfriends, #footballplayers." Vicki also posted the photo at left, but it was soon deleted.

This is amazing news, and now we just hope that we'll get to see this journey of Briana's throughout the upcoming Season 9. As you may recall, Briana and military man Ryan eloped in Las Vegas in 2011.

It's great that Vicki is so supportive of Briana, especially since they didn't appear to be on the best of terms at the end of last season. Vicki and Briana have constantly bickered about Vicki's relationship with Brooks Ayers, who made threatening comments about Vicki and Briana during a drunken conversation with Ryan.

Congrats to the happy family!
