Britney Spears Writes Letter to Fans, Reveals Next Single + Album Cover

Just like the line in her latest single, 'Work Bitch,' Britney Spears has clearly been working hard like it's her profession.

The tweet links to a long, handwritten letter to fans -- in which Britney says she is putting the finishing touches on 'Britney Jean' -- as well as an image showing that her next single will be 'Perfume,' dropping Nov. 5.

She has repeatedly stated that 'Britney Jean,' her eighth studio album, is her most personal work to date, and the attached cover art attempts to reflect that, showing a topless Spears looking deep into the camera.

"I poured my heart and soul into this album and it's been an incredible journey," Britney writes. "I have been through a lot in the past few years and it has really inspired me to dig deeper and write songs that I think everyone can relate to."

Promising there will be several "really fun, upbeat dance songs," she also reveals that collaborators on the album include will.i.am, William Orbit and Sia. "Of course, I also have some surprises for you guys," Britney writes.

She closes out the letter with a sort of personal manifesto: "I want to show you the different sides of Britney Spears. I am a performer. I am a Mom. I am funny. I am your friend! I am Britney Jean."

'Britney Jean' drops Dec. 3.
