Miami got even hotter when Thalia and Jennifer Lopez joined the fun at the 2013 Premios Juventud. On July 18, Thalia, J. Lo, her ex-husband Marc Anthony, with Chloe Green, "American Idol" runner-up Jessica Sanchez, Miss Universe 2006 Zuleyka Rivera, and more, celebrated at the awards show.

Thalia's Twitter followers were in full support of their idol, tweeting best-dressed praises at the "Manias" singer. Before Thalia performed her hit song onstage, she walked the red carpet in style. The 41-year-old Mexican telenovela superstar could easily be mistaken for a real-life Barbie doll. She sashayed into the Bank United Center in Miami with long, blonde hair and a sexy, white dress. Thalia kept it tasteful with her one-shoulder, draped number. The short dress skimmed her curves and showed off her legs. Thalia wore sparkling Christian Louboutin sandals and carried a white box clutch. The Latina's look would not be complete without the bling! Thalia accessorised with dazzling earrings and a stack of bangles.

Thalia had competition for best dressed at "Premios Juventud." Jennifer Lopez piled on the sequins in an eye-popping mini dress from Kristen Stewart favorite Zuhair Murad. Jennifer's boat neckline dress came in a web of gold fabric and was awash in gold and silver sequins. Metallic pumps and a sleek ponytail completed her look.

Jennifer also performed with Pitbull at the awards show. For her onstage looks, the "What to Expect When You're Expecting" actress rocked a pair of fierce bodysuits - another Zuhair Murad piece in black lace and a daring The Blonds number with gold chains. All that shimmer and shine no doubt matched the "Icono Mundial" and the acting award Jennifer Lopez received that evening!
