Jennifer Lopez Pictures Dancing With Casper Smart

Jennifer Lopez put on a sexy show with boyfriend Casper Smart last night in Hollywood. The duo performed her track "Dance Again" during the latest episode of American Idol. Following her dance duet with Casper, J Lo and her fellow judges, Steven Tyler and Randy Jackson, said farewell to American Idol hopeful Hollie Cavanagh. It was an emotional evening for the entire cast and crew, though Jennifer had the support of twins Max and Emme in the audience. The 3-year-olds showered Jennifer with hugs and snapped a photo with her at the judges' table.

The fun didn't stop there for Jennifer, since she made a quick change into nude shorts and Christian Louboutins for another event at the Bel-Air hotel. She was honored by Coty for her 10-year partnership with the brand. Jennifer's Glow kick-started the celebrity fragrance industry and has sold more than $1 billion in retail since it was first released over a decade ago. To celebrate the anniversary, Jen debuted a new scent, Glowing. Jen chatted with us during the event and said of her fragrance empire, "I don't think of myself as a beauty mogul in any way shape or form . . . it's mind blowing [the success], but I'm very proud."
