My favorite celebrities (there's a tie- sorry!) are Betty White and Chelsea Handler.
Why? Because in my book, nothing is sexier than a good sense of humor. Those two woman definitely have that. Plus, they're two of the few that really don't care if they're famous! I'm pretty sure they are both kind of shocked at how relevant they still are.
I have loved Betty since she was on Mama's Family, but the woman I idolize is Rose Nylund. At any rate, I think they're pretty close to being the same thing.
