As of recent Nick Cannon has been battling health issues. First being in the hospital due to kidney failure, now Doctor’s have discovered blood clots in his lungs. I pray he listen to his body and the Dr's orders so that he can be here on earth for the twins. Nick had this to say about his health:

My doctor was saying that my work is going to kill me – and he’s not joking. 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. Under doctor’s orders, I have been asked to cut back on some of my professional commitments to allow my body to get the rest it needs to keep up with the demands of my multitasking schedule. Even Superman has to sleep

Get well soon Nick Cannon, my prayers are with you.
