The 'Where Have You Been' singer was reported to be cancelling her summer stay in the UK due to health issues earlier today (June 7).
However, Rihanna later dismissed the claims, saying that she has just pushed her travel plans back to spend more time with her family.
A spokesperson for Wireless said: "She is still scheduled to perform at Barclaycard Wireless Festival."
Rihanna will headline the final night of the festival at Hyde Park, London on July 8.
Deadmau5 and Drake will headline the other two nights on July 6 and 7.
She is also scheduled to headline the second night of BBC Radio 1's Hackney Weekend on June 24.
