Iggy Azalea has confirmed that she will release 'Black Widow' as her next single.

The song features British star Rita Ora and it was co-written by Katy Perry.

The tune will be released in the UK on September 14 as she continues to mine her 2014 debut record 'The New Classic' for material.

'Black Widow' will follow up previous singles 'Work', 'Bounce', 'Change Your Life' and 'Fancy'.

The latter, which features Charli XCX, has enjoyed great success in the US and it has topped the chart for a number of weeks.
