As well as their 3-year-old twins - son Moroccan and daughter Monroe - the couple also shared their palatial New York City home with a large brood of four-legged friends.
Mariah, 45, and Nick, who turned 34 on October 8, married on her private island in the Bahamas on April 8, 2008, after just 6 weeks of dating, but separated in August.
America's Got Talent host Nick recently told US TV show Extra of the split: 'I’m just taking everything one day at a time and just being the best person that I can possibly be at the end of the day.'
Nick also revealed that he was still undergoing a procedure to remove the tattoo he had dedicated to the superstar.
"It’s not finished yet," he said. "It wasn’t supposed to be revealed yet."
"I had just gotten it done, it was painful. It hurt a lot and I’m still not finished, I’m still probably like six more sessions away."
Shortly after celebrating his birthday with an extravagant party in Las Vegas, he was photographed dining with a mystery brunette in New York City.
Reports have also linked him to newly-single beauty Amber Rose, although speculation of a romance between the pair has been denied.
