Life is pretty sweet if you're one half of the adorable duo known as Dem Babies.

Mariah Carey and Nick Cannon recently opened up their personal photo collection to the Fresh Air Fund, a group Carey works with regularly. The American Idol judge and her America's Got Talent host husband of four years posted adorable photos of their 16-month-old twins (affectionately dubbed "Dem Babies"), Moroccan and Monroe, swimming with their mama, hanging with their dad, and showing off their killer senses of style.

Recently, a source close to Carey told Us Weekly the Grammy winner and Cannon are going strong -- and revealed how excited Cannon was when Carey landed her new Idol gig.

"He thought it was such a great move for her," the insider shares. "Yes, the babies will be there [on set], and Nick too, when he can."

Adds the source, "I've never seen two married people more in love. Nick is the world's biggest Mariah fan. He totally believes in his wife."
