Ellie Goulding sipped on a cold drink poolside in Miami yesterday while relaxing under the sun in a striped bikini top and short shorts. She made her way to Florida on Monday to shoot a music video and joked on Twitter that she was in need of clothes for filming. Ellie's been busy working since the late 2012 release of Halcyon and one of her hit songs from the album, "Lights," is featured on the soundtrack for Spring Breakers, which hits theaters on Friday. Ellie's also gearing up to join Bruno Mars on select dates during his upcoming Summer tour. She'll take the stage solo before then with concerts scheduled around the world through April and May. Ellie will break from performing in late April, though, to run the Nike Women's Half Marathon in Washington DC on April 28.
