Turns out the biggest Bachelor drama doesn't always occur on-camera!

Some of the most beloved -- and infamous -- stars from past seasons of The Bachelor and The Bachelorette descended upon Breckenridge, Colo. April 1-2. The occasion? The 6th annual reunion of show alum, as hosted by Breckenridge native Jesse Csinsak -- and only Us Weekly was invited to the blowout!

Us Weekly's Jennifer Peros joined a who's-who of show alum -- including Vienna Girardi and new boyfriend Kasey Kahl, Britt Billmaier and Juan Barbieri -- for a weekend of snowboarding, skiing and of course, partying hard!
