What they wore: A psychedelic, rainbow colored, long sleeve Christopher Kane mini dress, retailing at $580.
When they wore it: The "I Remember Me" singer appeared on "Live! With Kelly and Michael" on September 5; J.Lo hit the town in the dashing dress at Hakkasan at the MGM Grand Hotel and Casino in Las Vegas two weeks later.
How they styled it: The "On The Floor" singer looked ready to party in the festive frock, pairing it with royal blue booties, funky geometric earrings, and a couple of chunky rings. She finished off her look with a pale pink pucker and sexed-up tresses. The former "American Idol" star looked hot to trot with polished locks, smoky eyes, and a pair of gold chain Giuseppe Zanotti peep toe heels.
Judge's scorecard: Normally we love J.Hud's style, but this time her pal J.Lo stole the show. The bright dress was much better suited for a wild night than a talk show and her fabulous footwear kicked the look up a notch.
