In what probably does not come as a surprise to any of you, Jake Pavelka and Vienna Girardi have split. Jake's publicist is the one who made the announcement but did not give away much. Jake broke it off. I'm guessing it was because Dancing With The Stars ended so the need to have someone watching him perform each week and pretending to be the happy couple was over.
I think Jake wants to go back to his have as many women each day as possible kind of life and that being engaged was kind of putting a crimp into those plans. As for Vienna, well, she might get one more chance at a full 15 minutes, but it's likely she will just fade away like so many others.
The whole thing was just a set up from the beginning. He wanted someone that would give him publicity, not a wife. Vienna did that for a while. Now he will try and latch on to someone more famous and keep struggling to book those club appearances.
