Bachelor executive producer Mike Fleiss is speaking out about the recent break-up of Jake Pavelka and Vienna Girardi, who became engaged during the show’s final rose ceremony in March. “It is painful,” Fleiss says in a statement to EW. “We’ve been on a roll lately with a bunch of happy couples in succession. Mr. and Mrs. Jason Mesnick, Ed [Swiderski] and Jillian [Harris], Ali [Fedotowsky] and ???… Strong relationships are even emerging from Bachelor Pad. This break-up caught me totally by surprise. I really feel bad for Jake and Vienna.” The reason for the break-up is not known yet, but Girardi tweeted Monday that rumors of her infidelity are false.
