Back of J Lo Performs Her Hits For Marc, Paris, Nicky, and the World Jennifer Lopez made a grand entrance at the World Music Awards in Monte Carlo this evening, escorted by Marc Anthony and wearing a full-length Roberto Cavalli animal print gown. She's been working on her tan aboard the designer's multimillion-dollar yacht off the coast of Monaco between spending time with her family, shopping and partying at Cannes events. Avatar's Michelle Rodriguez posed side by side with Heroes star Hayden Panettiere, who was modeling an up and away hair style and all smiles despite the recent canceling of the show. Hilton sisters Nicky and Paris made the evening a family affair, posing with their parents before handing out the award for best R&B artist. During the show, J Lo changed into a leg-baring Roberto Cavalli minidress to perform a medley of her hits. Paris Hilton was impressed by J Lo's act, tweeting a congratulatory message from the audience. Lopez later changed into her third Cavalli dress of the night to accept an achievement award for her contribution to music.

She is the only one that can pull off the plunging neck line... gorgeous! jenis1 7 years J.Lo always looks gorgeous.like the dress! jenni5 7 years I am shocked to see Michelle Rodiquez look so fem. She looks awesome. Love the dress and hair/make-up. jaan_black 7 years yawn, J-Low is over...and by now, we all know when she's heavily spray tanned and has her oil painter/makeup artist, she looks good...she was pasty and sad on some boat 2 days ago...anywho, Michelle Rodriguez, who I had written off as an alcoholic bum, looks fabulous and has some hot legs lemuse20 7 years WOW, I can't believe I'm seeing Michelle in a dress!! Louie 7 years Jennifer's dress could have been nice but I hate the skanky cut-outs. Love Paris's dress but not the skank wearing it. I don't get why the Hilton sisters are at Cannes in the first place. Glamorously 7 years JLo is so tacky! cherish28 7 years Every time I see her ugly husband, makes me vomit! His face has this thing, frowny face. They truly level together. Yes. ChicagoDiva 7 years I don't think her too-much-glitter-and-big-hair look is working for her anymore - it's time to transition to a fresher style, but she's a one-trick pony, and that's all she has. fifi8 7 years I'm glad someone likes her, because after seeing "The Back-up Plan," I wanted to back up to the closest toilet and "eliminate" everything I had consumed in the past ten days. Way to destroy a potentially promising career of Alex O'Loughlin, J.Lo. miss-malone 7 years I agree! She looks stunning in the leopard print Cavalli gown. :love: Glamorme 7 years Jennifer Lopez looks amazing. I truly think she looks better than she ever has, guess having kids doesn't always mean the demise of your looks.
