As Rita Ora aims to match the success of her debut with her forthcoming album, she readies another big single with another big collaboration. After cracking the Irish top ten and topping the UK charts with her Calvin Harris-assisted 'I Will Never Let You Down', Ora will be collaborating with current artist of the moment Iggy Azalea for 'Black Widow'.

The song, which was produced by Norwegian duo Stargate and features a chorus written by Katy Perry, Azalea has been something of a hot commodity this summer tying chart records set by The Beatles in the United States and currently sitting at the top of the Irish singles chart with her Ariana Grande collaboration 'Problem'

The single will officially be released September 14. Watch Ora and Azalea perform 'Black Widow' live for the first time at Britain's Wireless Festival 2014 below.
