But is still on for the festivals...
After the news that Rihanna is postponing a trip to the UK and cancelling an appearance on The Graham Norton Show next week, rumours were rife that she was stricken with all kinds of plagues and diseases.
The Sun claimed that RiRi had cancelled her trip because all her partying, boozing and general trotting around being sexy had made her ill - and Rihanna was quick to hit back.
"Nonsense! I'm not sick!" she tweeted.
"I pushed back my trip to London to spend time with my family. Sorry kiddos.
"The Sun Newspaper is like a f*ckin ass hair, full of shit!!!!!!"
Spokespeople for Wireless Festival and Radio 1's Hackney Weekend have confirmed that Rihanna is still scheduled to perform, so we won't start rocking back and forth with our head in our hands just yet.
