PHOTOS: Lindsay Gets Her Kicks - The Natural Way

Lindsay Lohan is pulling no punches.

The Mean Girls star, 24, was snapped Wednesday taking kickboxing classes at a gym in Hollywood, and RadarOnline.com has the brand new pics.

In spite of her recent troubles, the infamous Hollywood partgirl is riding the (natural) high of having a hit movie; Machete - which is generally getting good reviews - raked in $14 million in its opening weekend, placing it at number two at the box office, only behind the George Clooney thriller, The American, which came into number one with $17 million.
