That new Janet Jackson music making the rounds on the Internet is apparently not as new as you might think.

The pop superstar, who is working on a new album, says someone has leaked songs she recorded at least two years ago when working with hitmaking producer Rich Harrison. At least one song has already made the rounds, titled "Put It On Me."

"A couple of years ago I recorded some tracks with Rich Harrison. But none of that music will appear on my new album," Jackson said in a statement released to The Associated Press on Friday. "I have a tight rein on all of the music that has been recorded."

Jackson's new album, tentatively titled "20 Years Old," is expected to be released later this year. She hasn't released an album since 2004's "Damita Jo."
