Who's got the best job in the world? Well that would be the guy that gets to stick something between Isla Fishers legs and slap her ass while she works out. Read AND see more after the break.

Check out this semi-covert video of Isla Fisher working out. I really doubt that she didn't know she was being filmed since she is making orgasmic faces while tightening her butt. This is about as close to porn as you can get with clothes on. This girl's rear is shapely!  (and in case you wondered, this is the woman that married "Borat")
