"It's all rooted in love, it's all rooted in positive energy," Nick Cannon shares of the key to co-parenting twins Moroccan and Monroe with Mariah Carey

Nick Cannon is embracing the co-parenting dynamic.

The America’s Got Talent and Nick Cannon Presents: Wild ‘N Out host, whose divorce from Mariah Carey was recently finalized, famously split from the singer at the end of 2014.

And according to Cannon, the former couple has found a harmonious balance, to say the least, when it comes to parenting their kids: twins Monroe and Moroccan, 5½ — especially over this time of the year.

“I think that’ll be something that we’ll always embrace as a family and as our families expand,” Cannon, 36, tells PEOPLE of the upcoming holiday season, which the blended family kicked off by recently celebrating Halloween together at Carey’s costume bash.

“And continue to make sure that we keep everyone focused on love,” adds Cannon, who is gearing up to release a documentary called Why Real Is Rare, which focuses on how and when couples realize their connection is authentic. “That even goes back to what the documentary is all about — those real connections.”

Cannon explains that his upbringing involved a blended family, and that over the holidays he enjoyed going around to different houses and having multiple meals with different groups of people.

And at the end of the day, he admits it’s simply about the love and respect you have for each other.

“It’s kinda the norm. It’s all rooted in love, it’s all rooted in positive energy,” Cannon says. “There’s no hard feelings and ill will. Ultimately, it’s about putting the kids first and making sure they have the best childhood they could possibly have.”

The proud papa shares that “Roc and Roe” are developing quite the personalities.

“My son is the biggest ham in the world and loves deejaying. He deejayed the Halloween party, rockin’ the mic. It was crazy,” Cannon says, adding that his son’s love for deejaying started last year at Nickelodeon’s HALO Awards.

“This party was the first time I was like, ‘Man, do your thing.’ And so he was scratching and talking on the mic. And he’s seen me do it so much that he’s got the hang of it. So I think he’s gonna be taking Daddy’s job real soon.”

Of Roe, Cannon says, “And then my daughter’s a lot like her mom: loves to sing, loves to dress up. It’s a lot of fun.”

And is his little girl into boys yet?

“Let’s not talk about that,” Cannon jokes. “She definitely likes boys, and I’m trying to sway her in a whole different direction. Like, last year she told me she was getting married. I was like, ‘What!? You’re 4!’ ”

According to her dad, Roe’s Halloween costume was a representation of her actual personality.

“She’s a princess every day — that was just a princess costume from her closet,” Cannon says of his daughter, who dressed as Rapunzel from the 2010 Disney movie Tangled for Halloween while brother Roc was Mario to his dad’s Luigi and Carey went as a devil. “She has Tangled, Frozen, like every day there’s a different wig.”

The Drumline star shares that his little girl tends to dress like Carey, while Roc wants to look like his dad. And although Roe was quite prepared for Halloween, Cannon admits his and his son’s costumes were a bit last minute.

“An hour before [the party] he was like, ‘I’m gonna be Mario!’ ” he says. “And he had the costume and I was like, ‘I guess I gotta go get a Luigi costume.’ “
