Rihanna has revealed that her new track and music video for 'Who's That Chick' have been leaked onto the internet without permission.

The R&B singer's label has since released a statement via Twitter saying, "It’s a leak. Def Jam is pulling it down as fast as possible. The song is not a single - for the clubs only. The album is still being put together - many songs in the mix. Can't answer for sure if it is on the album."

The star also took to Twitter to address the video's leak, writing, "'Who's that Chick' is an online music video/commercial that we shot for Doritos and it got leaked...I don't want u to get confused...doritos is in no way connected to LOUD."

Rihanna is set to release 'Loud' in the States on November 16.
