DeAnna Pappas was rejected by Brad Womack on The Bachelor.
From there, she went on to become The Bachelorette and spurned Jason Mesnick in favor of Jesse Csinack. This made many fans very angry and upset. It didn't help any when DeAnna and Jesse proceeded to break up just a few months after the show aired (shocking, we know).
Pappas was somehow hired in 2008 as the host of a wedding series called Get Married. She also appeared on the finale of Mesnick's Bachelor season, doing all she can to remain relevant. Nothing wrong with that.
Gotta extend those 15 minutes for as long as one can!
