Musicians and longtime couple J.D. Samson and Sia have confirmed, via Twitter, that they have broken up. Sia tweeted a message to her fans that read, "A lot of you have been asking, yes, Mr. Boop and I broke up four months ago. We love each other and are still friends.

Sia, perhaps best known for her haunting song "Breathe Me" used during the finale of Six Feet Under, will begin a North American tour July 21 to support her acclaimed album We Are Born. Samson's new band Men recently played at the Coachella music festival. Who Took the Bomp?, a documentary that chronicles Samson's previous band Le Tigre was released on DVD last week.
