Rihanna has denied suggestion that she postponed a trip to London due to sickness.

It had been reported earlier that the superstar singer failed to board a plane to London yesterday (June 6), with a representative citing "sickness" as the reason.

However, Rihanna took to Twitter to dispel the sickness talk herself, stating that she postponed her trip to the UK to spend time with her family. She said:

"Nonsense! I'm not sick! I pushed my trip to London back to go spend time with my family! Sorry kiddos."

The Bajan beauty then later laid into British newspaper The Sun, proclaiming:

"The Sun Newspaper is like a f*ckin ass hair, full of sh*t!!!!!!"
