It's been several years since Missy Elliott released new material, but she's back with a bang, if her new single is anything to go by.

'WTF (Where They From)' is the highly influential rapper's first single since 2012 and features Pharrell Williams.

A comeback has been bubbling under since she appeared at Katy Perry's Superbowl halftime show earlier this year, and Williams is reportedly working on Elliott's new album, too - which will be her first since 2005's 'The Cookbook.'

She revealed in 2011 that she had been suffering from hyperthyroid disorder Graves' Disease in 2011, but had received treatment for it.
