Since the announcement of a new album and world tour, Janet Jackson fans have been wondering what to expect from the R&B superstar's new music. This morning, Jackson released "No Sleeep," the first single from her upcoming eleventh studio album.

The slow jam features Jackson's signature breathy vocals as she sings, "You're missing me/I'm missing you/Whenever we meet/We ain't gonna get no sleep."

"No Sleeep" was produced by Jimmy Jam and Terry Lewis, according to her official website.

The track is slower than her previous hits "All For You" and "Feedback," but it stays true to the classic Janet sound that she has perfected over the past three decades.

Jackson will kick off the Unbreakable World Tour on August 31 in Vancouver, according to Ticketmaster. Her album will be released later this year on Rhythm Nation Records/BMG.

"No Sleeep" is expected to hit the iTunes Store tomorrow, according to Rap-Up.
