The "Lights" are out for Ellie Goulding and Skrillex.

The British singer and her American electronic music producer boyfriend had been dating for about a year, but two sources confirmed to Us Weekly that they split. A source close to Ellie said it was just "a classic case of long distance being impossible." She’s based in the U.K., he’s based in L.A. There was no "bad blood" and they hope to stay friends.

Ellie, 25, performed her cover of Elton John's "Your Song" at Will and Kate's royal wedding in April 2011. She just released her second album, Halcyon. Skrillex, 24, whose real name is Sonny John Moore, recently won three Grammys and was named MTV's Electronic Dance Music Artist of the Year for 2011.
