Everyone on The Bachelor hates Vienna Girardi.

We're starting to understand the reason (or two reasons) why the only one who's opinion matters, star Jake Pavelka, has taken a liking to her, however.

ABC's official "bio" for Vienna Girardi, who has quickly become the enemy of every other girl left on the series, lists her as a "marketing representative."

Looks like they conveniently left out some of her free-time pursuits ...

Vienna Girardi sure can strategically wear a scarf, and clean up nice.

The above pic, unearthed by some site called Hollywood Life, is from a pinup calendar sent to over 2,500 clients and friends of C.O.D. Trees, Inc. of Oviedo, Fla., in 2009.

We have no idea what any of that means. What we do know is that it will surely fuel the fire for V's haters (as if rumors of her dating someone else weren't enough).

One wonders how Jake will feel when he finds out about this.

The Bachelor spoilers we've read project Vienna as one of the final girls standing. If that's true, we can see this (topless!) bomb being dropped on Jake soon enough.

You know Mike Fleiss is salivating over this ... possibly in more ways than one.
