Adrienne Maloof's Son Just Graduated Middle School ... And Paul Nassif Can't Believe How Big Their Kids Have Gotten, Either

Adrienne Maloof and Paul Nassif's son, Gavin, just graduated middle school. Yes, you read that correctly. And a photo The Real Housewives of Beverly Hills alum posted from his big day is all the evidence we need to prove that he's gotten quite grown-up looking. In fact, when Paul recently chatted with The Daily Dish, the Botched plastic surgeon also marveled at how big his three sons, including twins Colin and Christian, with his ex-wife have gotten: "It's funny 'cause I look at these kids and I look every year at how they sprout up."

Adrienne mirrored that sentiment, captioning the photo of Gavin at his graduation: "Happy graduation to my beautiful son Gavin. I love you with all my heart and soul. #mommymoments #timeflies."

While it hasn't always been smooth sailing for Adrienne and Paul since they split in 2012 after a decade of marriage, he shared that they have hit a stride when it comes to co-parenting their trio of sons — and they are definitely in a better place than they were in the past.

"This is a very important point that I want to make to you, especially for divorced people. Yes, Adrienne and I had a very public, maybe not the nicest divorce, but one thing that we both became very mature on and said, 'Hey, we have children and we need to pull together since we're two separate households. We need to come together as a team. We need to be consistent. We need to communicate with each other. We need to be good parents and make sure that these kids know that since there's two different households that we try to make it fun going from one house to the other,'" he shared. "We do things together with the kids a lot."

Their sons split their time between Paul and Adrienne and the former couple make a point of spending time together as a family as often as possible, including some holidays, and Adrienne even celebrated her ex at a recent event.

"We're really trying to make that sort of a household, so that it's not traumatic," he said. "I'm trying to basically say that if you're divorced, God willing, you can still take your kids and do a great job on them and really not have that be a big problem. Split-up households, sometimes, it's an issue, so when you come together as a team — and, yes, it's hard and you have to work through it — each couple has to win and lose. You have to work together and we've done a great job doing it and we've become friends, which is fantastic."
