Actor Simbu aka STR celebrates his 37th birthday today and around midnight the actor was pictured celebrating his special day with fans, friends and family. In these cliacks and the ones where STR has made recent appearances (actor Mahat's wedding being one of them), the actor can be seen back in shape.

While he awaits beginning his long expected project Maanaadu and the release of his next film Maha, one wonders if the body transformation is for beginning a new leaf in his career.
