When you're Jennifer Lopez you can go from rockin' sweatpants to rockin' the red carpet in a matter of hours.

On Wednesday, the mega star was out and about in Los Angeles in a grey sweatshirt, giant grey sweat shorts and the coolest pair of high top sneaks we've ever seen.

Other media sites balked at the Grammy winner's dressed down look calling it "drab" and "unflattering," but let's be honest, none of us look that amazing in sweats.

However, if the dressed down diva isn't your cup of tea, don't worry.

Several hours later, the "I Luh Ya Papi" singer switched up her low-key look for a seriously sexy dress for the live-taping of "American Idol."

The 45-year-old star sported a curve-hugging tan leather bodycon dress and polished off her look with a set of see-through Louboutins, a fluffy half-updo, smokey eyes and perfect neutral pout. Sorry Harry Connick Jr. and Keith Urban ... it's kind of hard to compete with that.
