SARAH'S WORKOUT BLITZ
No joke: Sarah Silverman has become a gym rat! Sources say that as she gears up for her 45th birthday next month, the often sardonic comedian who's joked in the past about using cocaine to stay slim has committed herself to healthy living. She's actually always been a fan of exercise, but she's really upped her game, says an insider, who adds that in addition to kickboxing and strength training, the longtime vegetarian has traded chips for green smoothies. Sarah can't wait to turn 45, says the source, “ because she looks and feels so great! ?
The truth-telling comedian recently joked to friends that she's determined not to be old and fat, says a source.
