Eminem is hard at work on his first studio album in three years.

The reclusive Detroit rapper called into New York radio station Hot 97 on Thursday, as his protege 50 Cent was doing an interview to promote his new album, and spoke about his own endeavors.

"I'm always working -- I'm always in the studio," Eminem said. "It feels good right now ... For a while, I didn't want to go back to the studio ... I went through some personal things. I'm coming out of those personal things (and) it feels good."

Eminem, who briefly remarried his wife Kim last year, jokingly said he'd release his new CD "tomorrow," though there is no official release date, according to Interscope, which distributes his releases.

Eminem's most recent solo album, 2004's "Encore," peaked at No. 1 on the Billboard 200.
