Taylor Swift and Alicia Keys brought US starpower to the red carpet at the NRJ Music Awards today in Cannes. Both arrived in France recently to attend the awards, which also attracted musical acts like Psy and One Direction. Things might get awkward for Taylor Swift, since she may run-into her ex, Harry Styles. He and his 1D 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 cut-out 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 pale gold sequined mini.
