Iggy Azalea has had one helluva week!

Los Angeles - Iggy Azalea has had a "hell of a week" but her fans' love has pulled her through.

The Fancy hitmaker's ex-boyfriend and former manager Hefe Wine is said to be in possession of a sex tape featuring the pair from when they dated and he has been offered a seven-figure sum to sell the footage to porn manufacturer Vivid Entertainment.

Iggy - who has denied the tape even exists - made reference to the problem during her sell-out concert at the O2 Shepherd's Bush Empire in London on Wednesday night, telling the crowd: "I've had a hell of a week."

But the 24-year-old rapper insisted the love and energy she was feeling from her British fans was making the drama in her life melt away.

She added: "Sometimes I think you can have the most awful, terrible week, but, for me, coming here and seeing your faces makes me realise I still have the best life."

Iggy took to her Twitter account to share her excitment for the show on Tuesday:

Hi England! can't wait for the show… Im hoping to see some faces i know in the crowd.

Iggy treated her loyal followers with a set packed with hits, including: Change Your Life, Work and a sexually charged performance of Bounce, during which she was joined by four leotard-clad dancers.

She also spat rhymes from Problem - her duet with Ariana Grande - and Fancy, her collaboration with Charli XCX.

The highlight of the show was when Iggy was joined on stage by Rita Ora for a rendition of their new single Black Widow. Iggy hid bizarrely under a white blanket with a grimacing face drawn on it and her name written on it.

Here is the official video for the hit new single:
