Blinded by the bling!

Jennifer Lopez dazzled in a gold sequined Temperley London cropped jacket (worn as a top) that revealed her toned tummy, plus coordinating metallic harem-style pants on the set of American Idol Wednesday.

The 42-year-old mom-of-twins accessorized the head-turning outfit with glittering heels, a chunky gold necklace and matching bracelet.

Last week on the show J.Lo wowed the audience when she hit the stage in a skin-tight silver Herve Leger by Max Azria bandage dress with sexy side cut-outs.

The superstar's stylists, Rob Zangardi and Mariel Haenn, love to dress the star in an array of flashy looks.

"We play with colors, styles and silhouettes," Haenn tells Us Weekly. "We call her 'Bronx Barbie,'" adds Zangardi.
