Jennifer Lopez Covers Vogue's Shape Issue: Behind-The-Scenes Video

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.
