Hmm... well the list always varies. Also, I don't have a significant other, so no reprecussions here!
But #1 on my list is and always will be
1.) Angelina Jolie
Then, Kristin Kreuk is usually #2, but not always.
Just add random hotness at #3 and beyond, for example:
3.) Mandy Moore
4.) Katherine Zeta Jones
5.) Adriana Lima
