The Weeknd drops out of Rihanna's Anti World Tour

Promoters say he can no longer open for Rihanna 'due to some unforeseen changes with upcoming projects'

The Weeknd has pulled out of his support slot on Rihanna's latest world tour.

Promoters Live Nation offered a rather vague explanation for his withdrawal, saying in a statement: "Due to some unforeseen changes with upcoming projects, The Weeknd will no longer be joining Rihanna on her upcoming international Anti World Tour."

The Weeknd - real name Abel Tesfaye - had been due to open for Rihanna at 32 of her European dates this summer, including five huge outdoor shows taking place in the UK and Ireland this June.

Live Nation has yet to announce if he will replaced by another support act at these dates.

Rihanna is currently embarking on the North American leg of her "Anti World Tour" with rapper Travis Scott as support.

During a recent show she was clearly taken back when she pointed her microphone to a fan who turned out to have an unexpectedly impressive voice.
