Mariah Carey has dubbed her next album "E=MC2," and will release it April 15; the R&B-leaning first single "Touch My Body" hit U.S. radio outlets this week.

The Island/Def Jam set comes three years after Carey's previous album, "The Emancipation of Mimi," which has sold 5.8 million copies in the United States, according to Nielsen SoundScan, and earned three Grammys.

The new album features production from the likes of Jermaine Dupri and will.i.am, as well as collaborations with R&B singer T-Pain and reggae star Damian Marley.

Other tracks expected to appear on the album include "Migrate," "Love Story," "Lovin' You Long Time" and "OOC."
