Britney Spears' New Track 'Alien' Leaks

According to British producer William Orbit, the leaked version of the new song has 'wrong chorus notes.'

A new song featured in Britney Spears' upcoming album, "Britney Jean", unexpectedly hit the web on Monday, November 18. The track called "Alien" is a pop ballad that finds the 31-year-old diva singing about her feeling misplaced like an alien.

"Cross through the universe to get where you are," she croons. "Travel the night riding on a shooting star/ Was lonely then like an alien/ Had to get used to the world I was on/ While yet still not sure if I knew where I belonged/ That was then, like an alien."

"Alien" was produced by William Orbit, who has previously worked with the likes of Madonna and Blur. The British producer has reacted to the song's early arrival, saying on Twitter that the finished version will be different from the leaked one.

"It's the wrong version of 'Alien' that's out there," he said. "Right song, but had wrong chorus notes, [now fixed] on THE version."

"Alien" is the fourth song off "Britney Jean" that fans have listened to. Spears released the album's lead cut, "Work B**ch", last month. Earlier this month, she released the second single "Perfume". A few days later, a song entitled "Passenger" managed to make its way out online. Spears' eighth studio effort is set to hit the stores on December 3.
