As the singer gears up for the Sunday afternoon performance for the American Music Awards with rapper Iggy Azalea, let's take a quick look inside the beauty regimen of Jennifer Lopez. It is now revealed that the gorgeous singer and actress known for her toned pins actually spends a fortune to keep them in shape.

According to a new report, diamonds are the secret behind the singer's well-toned and shapely legs. An Australia-made body scrub made up with diamond powder is a beauty secret the American beauty swears by. The Mirror told that this diamond body scrub is worth $250 per bottle.

A close source has revealed that Lopez's legs are prone to cellulite. Whenever the singer gains weight, the first signs appear on her legs, especially on her thighs. The said scrub helps keep away the cellulite from these parts. The Australian-made diamond body scrub has reportedly worked wonders to keep the singer's legs fit and free from extra fat. Since the 45-year-old musician has started using the diamond scrub, her legs have never looked better and are in perfect shape.

It is also reported that the American beauty uses spray tans on her legs to make them more attractive. A source told OK Magazine that Lopez is quite fond of these sprays, finishing off bottles within one month. She believes that these sprays not only help her leg remain smooth and attractive, but also make her tan stay for a long time.

Lopez's personal trainer also revealed earlier that the 'Booty' hitmaker undergoes 90-minute workout sessions daily, which keep her abs and overall body fit and attractive. Her workout session includes muscular structure work of around 10 to 12 exercise routines. These exercises were also changed and modified after every 10 days to stretch and tone every muscle of the body. Dance aerobics is also another secret and passion of the popular singer.

The organizers of the event have set the ground rules for Lopez and Iggy's performance, which included a ban from revealing bottom cracks and no rubbing on each other while performing on stage. The whole show will be broadcasted on TV with three- to four-minute delays to give the networks the chance to censor out anything if needed, as told by TMZ.
