Nick Cannon wants to keep the number of celebrities in his household to a minimum.
The America's Got Talent
host, 30, says he will "absolutely not" let his 4½-month-old twins
, Moroccan and Monroe, follow in the famous footsteps of him and wife Mariah Carey
"I just want them to strive for something greater than entertainment," Cannon told PEOPLE backstage after Wednesday's AGT
's season finale. "I'm one of those believers in teachers, professors, heart surgeons. That's what I'm rooting for. If I could get a scientist, that'd be amazing."
Even though fame isn't the path Cannon wants his children to take, he says it's the right road for him and Carey.
"My wife is so understanding because she's just as busy and just as focused as I am, so it's kind of like the perfect match," he says. "I love my career and I love being in entertainment, so it never really feels like an occupation."
Still, Hollywood isn't top priority for Cannon. "Being a father and being a husband comes first," he says.
"Everybody knows I'm obsessed with my wife," he gushes. "I'm married to Mariah Carey. It doesn't get better than that. I'd be an idiot to do anything wrong. I worship my wife. Have you seen my back? My back says 'Mariah Forever.' "
