Taylor Swift and Alicia Keys brought US star power to the red carpet at the NRJ Music Awards this evening in Cannes. Both arrived in France recently to attend the awards, which also attracted musical acts like Psy and One Direction. Tonight may be an awkward one for Taylor Swift since she may run into her ex Harry Styles of One Direction. He and his bandmates Zayn Malik, Niall Horan, Liam Payne, and Louis Tomlinson hit the carpet as well. Both Taylor and Alicia had stunning — though different — looks before the show began. Alicia wore a cutout Michael Kors gown, with husband Swizz Beatz on her arm, and apparently got a great reception. She tweeted, "France, I can feel the love!" Taylor, meanwhile, donned a sequined gold mini from Elie Saab.
