Photo: Check Mary J Blige out!!!

Mary J Blige (42) graces the front cover of 'shape'mag. in which she flaunts washboard abs in a two piece.
Her fitness overhaul began in February 2012 when Whitney Houston died suddenly from an alleged accidental overdose. Reeling from the shock of the iconic singer's passing, Mary rid alcohol from her diet for 15 months and got serious with a new personal trainer.
The diva's workouts are a focused around cardio, which means the star goes running for six to eight miles a week. But pounding the pavement isn't the only way she toned up. The actress recently learned how to swim, something she's wanted to do for decades.
All her hard work has definately paid off!!!
