Not everyone can pull off a denim-on-denim look, but then again, not everyone is Jennifer Lopez.

The mother of twins proves just how well she can wear a Canadian tuxedo in her latest Instagram photo, which shows the singer flaunting her washboard abs in a denim crop top and matching jeans. 

A closeup snap of Jennifer's enviable tummy was posted by her stylist Rob Zangardi with the caption 'Guess who?!!'

So how does the on-the-go singer, actress and entrepreneur keep fit?

Jennifer reportedly follows a strict no salt, no sugar diet and exercises portion control. She also never goes two days without a workout, despite her busy schedule.

The star shares two children, Max and Emme, 5, with her estranged husband Mark Anthony. She’s been dating backup dancer Casper Smart, 24, since early this year.
