It's HOT here in Los Angeles today and Lindsay Lohan attempted to cool off while on the set of 'Labor Pains' by lifting her shirt and exposing her toned stomach.

I've seen Lindsay Lohan in a bikini about a million times and I've seen her naked but for some reason there is something oddly sexy about seeing a chick's bare midriff when you're not supposed to. The only thing I can equate it to is returning from the field after a hard day of not dying in 1630 to see the neighbor's daughter during a furious bout of butter churning and accidentally getting some hot uncovered Puritan ankle action.
