Renewing one's wedding vows is typically a once-in-a-lifetime experience. But Nick Cannon and Mariah Carey prefer to do it a little more frequently than that – like every year!

"I encourage everybody to do it. If you are happy and in love, celebrate it!" Cannon, 29, said Friday on his New York radio show, confirming that he and his pop-star wife, 40, will renew their vows – for a second time – to celebrate their second wedding anniversary.

"Don't everybody do that?" the America's Got Talent host asked. "Don't, like, Heidi Klum and Seal do the same thing every year? It's just something fun to celebrate. We renew our vows and exchange gifts."

Their anniversary is this Friday, but as of last week, the couple hadn't settled on a final plan for this year's celebration. They wed in 2008 on Carey's Bahamian estate, but aren't looking for an island getaway this time around.

"We did that last year and the year before that, too," says Cannon. "This year we want to do it like in a normal setting, so it might be in L.A. … Hey, I say we do it in a church in Brooklyn. That will be hot."

Cannon says his gift to Carey this year is "something very thoughtful and it has nothing to do with money." And he adds: "We are just trying to keep the romance alive. That's all."
