Nick Cannon is "doing great" following his split from Mariah Carey.

The 'America's Got Talent' host, who recently announced he'd separated from his wife of six years in June, is holding up well, according to his close friend Nelly.

The 39-year-old rapper said: "I think he's doing great. I don't know if you've seen him, but he's cut his hair. He's looking like he's been back in the gym, got new tattoos."

The 'Real Husbands of Hollywood' star has been giving his co-star space to get over the split.

He said: "When Nick is ready to let us in on that, I think he will. I think it's one of those things, because you are a friend, you have to be a friend first. So you don't push on issues like that. You joke around it, but you know how far to go with that. Nick will let us know how far to go."

Meanwhile, Nick also admitted he is taking life "one day at a time" at the moment.

The 34-year-old star, who has three-year-old twins Monroe and Moroccan with Mariah, has been throwing himself into his work recently.

He told PEOPLE.com: "That's why we all entertain, to put a smile on others' faces. I take that as a lifelong goal, but still, at the same time, take it one day at a time."

He added: "Ultimately I would think that is what life is all about, to try to pursue happiness, and I try to wake up and take each day with a grain of salt, and say, 'How can I be happy today? How can I affect someone else's day, and hopefully make them happy?' "
