UPDATE: Vienna's announcement comes as a surprise to Playboy.
"This is the first we've heard of Vienna Girardi appearing on the cover of Playboy," a rep for the magazine told Us Weekly. "We are not in negotiations with her and have not made her an offer."
"I am going to be on the cover of Playboy later this year," Vienna tells Star. "The Bachelor didn't pay me a dime, and I ran through my savings living with Jake. I need the money. And I want to do something fun and happy for myself!"
Vienna's story conflicts with that of a friend of Jake's who said she fleeced him out of thousands of dollars as he paid for everything during their brief engagement.
Vienna hopes to get a $250,000 payday from her shoot, according to Star, which probably means she plans on taking everything off.
