The singer - who welcomed Moroccan and Monroe into the world on April 30 - has now left hospital, and her husband Nick Cannon is overjoyed because for the first time it will just be the four of them with no medical professionals around.
Speaking on Saturday (14.05.11), Nick said: "My twins came home today. It`s a whole other level now because they`re at home.
"There`s no hospital rooms, and there`s no nurses, it`s just us. So, it`s real. It`s a little scary at times, but we`re handling it."
`America`s Got Talent` host Nick has found it particularly hard to be away from the twins, something he wasn`t expecting.
He told `Access Hollywood`: "I didn`t know it was going to be this tough to leave home every time! Like, I left the hospital to go to New York to do promotion earlier in the week - that was tough. But I`m dealing with it."
Mariah is also doing well at home, with Nick adding she was looking "beautiful".
He said: "She`s up and walking around. It`s beautiful - she`s a mommy!"
