Nick and Mariah's twins have finally been released from the hospital and are now settled into their lavish nursery at home with their parents. But the new dad has found it surprisingly difficult to leave behind the family when job duties beckon.

“My twins came home [today],” Nick told "Access Hollywood" at the KIIS FM Wango Tango concert in Los Angeles Saturday night where he acted as DJ. “I didn’t even want to leave, but I had to because I’ve got to be here."

“This was very tough,” he continued. “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. And then this was tough too! But, I’m dealing with it.”

And when the 30-year-old comedian/radio personality is home, he's busy getting used to his new role and enjoying every bit of it.

“It’s a whole other level now because they’re at home,” he said. “There’s no hospital rooms, and there’s no nurses, it’s just us. So, it’s real. It’s a lil’ scary at times, but we’re handling it.”
