Ryan Seacrest

Geez, Ryan Seacrest goes through women like he goes through breathmints!

Two days ago, we spotted him with 2007 Playmate of the Year, Sara Jean Underwood (no relation to Carrie), and now he's looking all lovey dovey with some other chick. The two were spotted on Nikki Beach in St. Barth, and we're wondering just how many girls Ryan brought along on his Caribbean vacation!
