Famous Love
We've found a scientific method for rating a couple's "hotness," based on four criteria: Success, Attractiveness, Popularity and Staying Power. Here's how it works.

Popularity
This is where we get nerdy. We checked how often each person is searched for on Google every month, so Katy Perry annhilates the model who married Mark Wahlberg.

Success
It's all about the Benjamins! The hottest stars are always bringing home the big paychecks, but Oscar, Grammy wins and critical acclaim don't hurt either. It's all about excelling in your own field, with special consideration given to achievements in the past year.

Attractiveness
True hotness requires good looks. A team of twelve editors have rated each couple's attractiveness on a scale of 1-10. We've used the average of all twelve scores for each couple.

Staying Power
They may be on fire, but if a couple isn't going to last, they won't fare well on our list. Engagements, marriage, babies and longevity help us determine who dominates this section.

All of these add up to a cumulative average, thus their spot on The List.
