Tracy Morgan

In 1996, the ’Saturday Night Live’ comedian discovered he had type 2 diabetes. He didn’t take his disorder seriously for several years until he had to undergo a kidney transplant in 2010 after suffering from type 2 complications and excessive alcohol consumption.

Morgan thanked his former girlfriend Tanisha Hall whilst on the red carpet of the 2011 SAG Awards for saving his life.

He said: "I'd like to thank Tanisha for donating my kidney to me."
