Mariah Carey is still That Girl, but her album won't be titled that anymore.

The singer said in a statement Tuesday (February 12) that her upcoming album, will now be called E=MC² instead of the previously announced That Girl. The forthcoming 11th studio album, the follow-up to her critic-approved The Emancipation of Mimi, is due April 15 on Island Def Jam.

The album's first single, "Touch My Body," which she wrote and produced with Tricky Stewart and The-Dream (the duo behind Rihanna's "Umbrella"), is set to hit radio Tuesday. The video for "Touch My Body" will be directed by longtime collaborator Brett Ratner, who helmed prior Carey clips such as "We Belong Together," "Heartbreaker" and "I Still Believe."

When Carey appeared on "TRL" in October, she offered a few hints regarding her album. She was promoting her fragrance, M by Mariah Carey, and said that creating the perfume and working on her album influenced each other.

"I've been working on this record while I'm working on the fragrance," she said. "I wanted [the fragrance] to be sensual. ... It's really been like writing a song. ... This was almost the same creative process."

Carey also mentioned in October that she "just had a really, really hot session with somebody in Miami." She didn't name names, but producers Cool & Dre told MTV News about various sessions they had with the singer.

"With Mariah, one of her favorite records is 'New York' [by Ja Rule], and she asked us to do a record like that," Dre said. "It was like, we got an opportunity to work with Mariah, and she wants us to do something we already did. But we said, 'You know what? You don't get too many opportunities to work with a Mariah Carey.' And to know you have her ear, you got to impress. So me and Cool decided not to do 'New York.' We wanted to show her we could do big pop records too. We turned it in, and her A&R came back and asked us to go gutter instead. So we made the hardest beat ever in history. We had a bunch of rappers trying to steal the beat, and they couldn't believe we made the beat for her. Jadakiss, Busta Rhymes, all saying they couldn't believe we were giving it to her. And then, she ended up taking the first record anyway."

Other artists scheduled to contribute to E=MC2 include Jermaine Dupri; DJ Toomp (Kanye West, T.I.); Stargate (Ne-Yo, Trey Songz); Will.I.Am; Bryan-Michael Cox (Usher, Mary J. Blige); Danjahandz (Justin Timberlake); and Philadelphia soulster James Poyser (Erykah Badu).
