Britney Spears debuted her new single "Perfume" on Sunday, and the pop star tweeted a link to the tune and wrote, "This is like sharing a piece of my heart <3."

The song is from Brit's upcoming album, Britney Jean, and she previously admitted that several tracks cover the fallout from her split with Jason Trawick. "After having a huge breakup this year, I had a lot to say in the studio, so it was really nice to have a therapy like that and to be able to share that with my fans … so it's a real personal album," she told Ryan Seacrest back in September.

Britney sings, "I want to believe it’s just you and me / Sometimes it feels like there’s three of us in here baby / So I, wait for you to call / And I try to act natural / Have you been thinking ’bout her or about me / And while I wait I put on my perfume, yeah I want it all over you / I gotta mark my territory..."

Was Jason cheating on Brit Brit!?
