Jennifer Lopez's once most-talked about and much-envied bootylicious bottoms are receding and how?

Don't get us wrong! The mom of two hasn't missed a beat in her career and has looked flawless ever since she stepped onto the scene.

Given that it's been15 years since she first shook her derriere onstage, it's natural that things have changed for her ridiculously gifted rear.

Flashback to 2003 in Manhattan red carpet premiere, J.Lo in a skintight tan gown highlighting her sexy silhouette would have given Kim Kardashiaan a run for money.

Her Manhattan appearance was clouded by her scandalous Versace Grammys gown years prior, but her killer rear was definitely there.

Then there was her Jingle Ball performance that year where she opted to wear skin hugging high-waisted pants that showed off her enviable curve.

And let's not miss out those numerous photo shoots over the, many of them displaying her butt with aplomb.

And just a couple of years back, the brunette beauty was captured vacationing with her then-hubby Marc Anthony in a teeny-weeny red bikini that revealed it all.

Cut to last evening, the "First Love" singer made a stunning appearance on the Late Show with Jimmy Fallon in a low-cut, white cocktail dress, with plunging neckline. And while she tried to draw all attention to her ample cleavage, we couldn't help but notice her flattened derriere.

So is it just the dress or J Lo's really losing out on her prized possession. What do you think?
