Kate Upton is probably the most popular model in America.

She was on the cover of the 2012 Sports Illustrated Swimsuit Edition and has been featured in many internet videos that have gone viral, such as the Cat Daddy and Dougie videos. Most recently, she has been in the news for being linked to Detroit Tigers pitcher Justin Verlander.

Paulina Gretzky hasn't had the success of Upton, but lately she's been creating close to the same amount of buzz as the supermodel.

The daughter of hockey great Wayne Gretzky has made headlines on numerous occasions for posting racy pictures of herself on Twitter and Instagram. She made news this week when she uploaded a photo of herself in a bikini, while on the set of Adam Sandler's Grown Ups 2.

Model Kimberly Alexis Howe was in the picture alongside Gretzky.

Both Upton and Gretzky have become internet sensations with their photos and videos, but which woman is hotter?

Below are pictures of Kate Upton and Paulina Gretzky.
