With the American Music Awards in full swing this week, and the amazing Jennifer Lopez taking over hosting duties we found choosing only one of her spectacular outfits quite the difficult duty. In true JLO fashion, the flawless diva delivered one sparkly, revealing look after another. From a stunning canary caped jumpsuit by Micheal Costello to a see-through embellished Balmain number, Jenny From The Block never lost our attention. Our favorite look of the evening came in the form of a total princess moment by Micheal Cinco. The shimmery confection was the perfect mix of award show sparkle and on-stage drama. Selena Gomez also caught our eye at the show in a ruby hued dress by Givenchy. Ms.Gomez can often try a bit too hard to look sexy, but this dazzling little frock was not only event appropriate, it delivered just the right amount of smolder. A pleasant surprise this week came in the form of a red hot Tom Ford gown worn by Mother Monster herself. Lady Gaga is usually out there when it comes to fashion, but this laser cut stunner was a major win for the songtress. We even can applaud the matching gloves and her subtle use of jewelry. On a more polished note, Amber Heard was a picture of sophistication in a menswear inspired Dolce & Gabbana suit. There is something timelessly chic about a glamorous woman dipping her toes in the androgyny pond. Plus, when you are on the arm of Johnny Depp you have to make a statement all your own.
