Nick Cannon has been rushed to hospital with two blood clots which are said to be "serious."

The America's Got Talent judge was hospitalised last Friday and was treated by doctors for two blood clots in his lungs and an enlarged ventricle in his heart, after his immune system began attacking his organs.

Speaking of his ordeal on his 92.3 NOW-FM show, Nick said: "I have been in the hospital since Friday, and actually, it's quite serious. I didn't even know."

"I was actually trying to downplay it a lot - even in my own mind - not go to the hospital because I was having a lot of pain in my back and I thought it was the typical kidney pain that I had been experiencing, but I thought it had been a little bit heightened."

Nick was told by his doctor that he should be fortunate for having a fit and in-shape body because if he was unhealthy, he would have died from the clots.

After being ordered to cut down his work load, Nick has realised that he needs to take care of himself to look after his family. "I think part of the reason why my health did kind of deteriorate was because I wasn't resting a lot and I was doing too much. I was overworking myself, working out too much," he said.

"I always took a lot of pride in working so hard and never taking a day off. But I'm learning that it isn't the wisest thing all the time, especially being a new father. Not only wanting to spend more time with my children, but wanting to be there for my children."

Nick has suffered a series of health issues recently, and spent the Christmas period in hospital after suffering kidney failure.
