Janet Jackson is back with a bang. The 49-year-old singer took to Twitter Monday to debut "No Sleeep," her new single from her upcoming yet-untitled album.

"I dedicate this to My Love," the singer wrote on Twitter along with a hashtag #ConversationsInACafe. The hashtag fueled speculation it might be the name of her new album. "No Sleeep" is the first song released by Jackson in seven years. Her last album, “Discipline” was released in 2008, debuting at No. 1 on the U.S. Billboard 200, and became her sixth work to top the charts. “Discipline” was also Jackson's first album to reach top spot in the United States after “All for You,” which was released in 2001.

Jackson's longtime friends, Jimmy Jam and Terry Lewis, produced “No Sleeep.” The song is available to purchase via BMG and Jackson's record label Rhythm Nation. The new single from her upcoming 11th album sees the songstress crooning about how much she misses her lover.

"Whenever we meet, we ain't gonna get no sleep,” she whispers. "It's going to be a weekend marathon / so you better get ready my king / 'cause I'ma be the queen of insomnia," she sings. "Stay wide awake / for every moment we spend together/ Cause every second you're awake feels like forever."

Last month, the six-time Grammy winner also announced her 36-date "Unbreakable World Tour." The tour kicks off Aug. 31 at the Pepsi Live at Rogers Arena in Vancouver and will see Jackson playing in 32 cities worldwide. Various artists, including Ciara, are also expected to pay a tribute to Jackson Sunday when she appears at the BET Awards, Page Six reported, adding she will make her comeback at the event.
