Lindsay Lohan bared her midriff yesterday while on the set of her new movie Labor Pains which is currently shooting all over the SoCal area. Dressed as a baseball player, Linds tried to cool herself off as best she could by lifting up her shirt to try and cool off her tummy … here are a few pics:

Dang, Lindsay‘s got a great bod. A few summers ago, Lindsay was rail thin with bones protuding from every part of her body (you may recall that she had been spending a lot of time with her then joined-at-the-hip BFF Nicole Richie who was also rail thin — I had dubbed them The Skeletwins^TM) but these days she’s lookin’ healthy and happy … and hot, literally. It can’t be easy filming scenes like this for a movie when the temperature soars into the high 90′s (like it did yesterday). It looks like Linds is hanging in there like a champ. I like the healthy new Lindsay, workin’ hard when it’d be easier to just bail and skip out on responsibilities (like she did last summer while working on Georgia Rule). I hope all this hard work does pay off for her in the long run. The positive reinforcement would do wonders for her continuing health and happiness.
