Now that's friendship.

Tracy Morgan revealed his kidney donor's identity at the Screen Actors Guild Awards on Sunday.

"I'd like to thank Tanisha for donating my kidney to me," the 30 Rock star told E!'s Giuliana Rancic on the red carpet. Morgan had a kidney transplant in December.

But, who is Tanisha? The generous woman is presumably Tanisha Hall, who Morgan began dating after divorcing his then-wife Sabina in the fall of 2009.

"We were together, but then we separated," Morgan explained. "But she also gave me a kidney."

Morgan then ended his interview with a strange and sudden shout-out: "Sarah Palin, you're the hottest MILF in the world! She's a MILF!"
