This Hills Alum Is Expecting A Brand-New Family Addition

The bouncing baby will arrive in a few short months!

Frankie Delgado was known for having a large Hills crew (never forget those nights at Les Deux) -- and now the same can be said for his family life. That's right, the MTV alum is expecting his second child with wife Jennifer!

"Most beautiful pregnant woman ever! 3 more months .. Happy Bday baby," Brody Jenner's BFF -- who is already superdad to two-year-old daughter Isabella -- captioned the snapshot of his ladylove and second kiddo above. Jennifer sweetly commented on her hubby's pic with a short and sweet "love you."

Frankie's impending arrival joins a bunch of Hills munchkins -- including Audrina Patridge's infant Kirra, Kristin Cavallari's three children and Holly Montag's son Isaiah. Group playdate for all the kiddos, please!

Be sure to offer your congrats to the Delgados, and for a fun rewind, check out an old-school Hills clip featuring the soon-to-be papa-of-two (talking about Ryan Cabrera, of all things!).
