The 'I'm Into You' singer says she feels comfortable with her body shape and enjoys staying fit.

Jennifer Lopez has opened up about how she stays in shape in a brand new video charting her upcoming cover shoot for Vogue US.

The 'On The Floor' singer features on the cover of the magazine's Shape-focused issue, and dons a scarlet red flowing dress for the photo shoot.

American Idol judge Jennifer admits in the video that being a mother can make staying in shape more difficult, but says the nature of her job as a pop singer helps her to stay fit more easily.

Jennifer also discusses her own body size and shape, and says she feels comfortable with fluctuating between size 4 and 8 (US sizes) depending on whether she is gearing up for photo shoot or taking a break from work.

Earlier this week the 'I'm Into You' singer was pictured filming scenes for a new music video in Mexico alongside her boyfriend Casper Smart.
