It's another boy! Real Housewives of Orange County star Vicki Gunvalson revealed on Facebook on July 4 that her daughter Briana Wolfsmith-Culberson gave birth to her second child.

"Just got to LAX to catch a 6am flight to OKC. Our new baby decided to come a early," the reality star announced on her page, "Can't get there quick enough! Pray for healthy baby and momma. 4thofJulybaby."

Gunvalson is already a proud grandmother to Briana and husband Ryan Culberson's first child, 22-month-old son Troy

The self-described "Nana" was equally as excited when her daughter and son-in-law learned the sex of their second child. Back in January the Housewives veteran posted a picture of the clan with blue balloons along with the caption: "So excited! Just found out baby #2 is a BOY! #troybigbrother #bestfriends #footballplayers." The adorable moment was also featured in an episode on this season of Real Housewives of Orange County.

Briana, who now lives in Oklahoma with Culberson, wrote in a blog post in 2013 that since having Troy, she's found a better appreciation for her mom, whom she openly has fought with on the Bravo series. 

"Having Troy has allowed me to feel more empathetic for my mom and how amazing she is as a mother," the nurse wrote. "Throughout my life she has always put my brother and myself first and was always focused on our happiness. If I'm half as good of a mom as she is, then I'll have done something right."
