OK Jen, this is for you....

I went to http://www.myheritage.com and this is what it came up with for me.

62% Charlize Theron
56% Catherine Zeta-Jones
55% Gwen Stefani
53% Justine Henin-Hardenne (Isn't she a tennis player?)
53% Marcia Cross
52% Farrah Fawcett
51% Frank Lampard (WTF? I look like a dude?)
50% Angelina Jolie (Now that's more like it!)
48% Keira Knightley
47% Cameron Diaz

So there you have it.
