The 30 Rock star had a kidney transplant in December 2010 but kept his donor’s name a secret. During an interview with E!‘s Giuliana Rancic, he said:

“I’d like to thank Tanisha for donating my kidney to me.”

Tanisha Hall dated Morgan after he divorced his wife in the fall of 2009. He added:

“We were together, but then we separated. But she also gave me a kidney.”

That’s quite a gift to give someone you’re no longer with. Thanks for keeping Tracy alive, Tanisha!
