The Jake Pavelka-Vienna Girardi break-up -- Jake broke it off [UPDATED]

jake-pavelka-vienna-girardi-gregory-michael.jpg UPDATE: TMZ now has Vienna's side of things. A source close to her says that she was not stepping out on Jake, but instead she was the one who ditched him because he was being a "fame whore" who didn't want to work on their relationship. Oh, what a tangled web we weave when first we practice to go on shows like "The Bachelor."

It is a sad day indeed for fans of the "Bachelor"/"Bachelorette" franchise. Late Monday night (June 21), Jake Pavelka and Vienna Girardi announced they were splitting up. Their rep tells OK! magazine, "Jake and Vienna have split and appreciate respect for their privacy at this time."

But now TMZ is reporting that Jake is the one who ended things -- apparently because he suspected Vienna of cheating on him with Gregory Michael of ABC Family's "Greek." Gregory and Vienna were seen flirting this past weekend in Santa Monica so who knows?
