The upcoming season of X Factor promises plenty of drama, judging from the pre-show buzz. This week, an apparently disgruntled former contestant posted a previously unreleased Britney Spears track on the Internet... complete with his own vocals.

Singer Don Philip, who once duetted with Spears on a ballad from her debut album ...Baby One More Time, posted the 2010 demo "Pleasure You" to SoundCloud on Wednesday. The leak comes several weeks after Philip had an emotional reunion with Spears at an X Factor audition — one that didn't go particularly well, judging by his catty remarks on Facebook shortly thereafter:

"Back to real life…all my demons released… i totally crocked when the pressure was on… at least I didnt shave my head…my vocal chords tightened up like a snake around a mouse..lol and the vipers cam out with fangs… a couple tears later..and I am standing tall.. I am free and God is good. I know some people say I havent taken care of my vocals over the past ten years..but its funny my worst is there best..minus autotune..its all good..I AM DON PHILIP TRACK IM FINISHING WITH GOMINATION NEXT WEEK…LIFE IS GETTING BETTER..SAY WHATS ON YOUR MIND BE WHO YOU WANT TO BE..BE PROUD.. I AM NOW."

The song, which was reportedly recorded in 2010 during a studio session for Spears' most recent album Femme Fatale, features some surprisingly deep vocals from Britney, who almost sounds like Toni Braxton at some points. It also has guest vocals from Philip, although it's not clear whether he was featured in the original recording or if he added them to the track himself.

Listen to the track below. Are you surprised it didn't make the final cut?
