Answer by C. M. Latsha:
My vote is for Danica McKellar. Best known as Winnie Cooper in the The Wonder Years, she went to UCLA, and graduated summa cum laude in mathematics. That's mind-blowing. Sure, she was a cute teenager, but what's she like as an adult?
Yeah, she's still at least a 9.
She's got an Erdos number of 4, which is like a Bacon number for Paul Erdos, a famous mathematician. Since she has a Bacon number of 2 (via Christopher Guest), she's apparently one of the very few human beings to have an Erdos-Bacon number, with a mind-blowingly low number of 6.
