Nick Cannon has "no muscles" following his recent health problems
The `America`s Got Talent` host - who was stricken by mild kidney failure over the festive period - is feeling much better, though he is unhappy with his appearance and his condition means he will find it hard to get back in shape.
He tweeted: "Getting back in shape is going to be tuff, the DR said because of my condition my body can`t process protein and that`s what builds muscle
"Time to work smarter not harder... but I got to get right by the time America`s Got Talent starts!
"It`s going to be difficult to get my six pack back on this Renal Diet. No muscles, skinny with a gut is not fresh
"Right now In my tanktop I look like Samuel L. Jackson in Black Snake Moan #needtogetbackinshape (sic)"
Though Nick - who has nine-month-old twins Moroccan and Monroe with wife Mariah Carey - is on the mend, he returned to hospital on 25.01.12 for a "scheduled procedure".
He tweeted: "Back at the hospital, but no worries its only for the day. I will be back at work tomorrow!
"Not an emergency. This was a scheduled procedure. I just dislike hospitals."
Meanwhile, Mariah is reported to have splashed out $300,000 on a Ferrari for Nick.
The luxury automobile is said to be a get well present for her spouse, Media Take Out have revealed.
