Katy Perry And Rihanna Rock In Rio

'California Gurl' Katy Perry hooked up with her 'We Found Love' BFF Rihanna to party in Rio.

The pair were both in Brazil to perform at the Rock In Rio event this weekend, but they managed to squeeze in some time to say 'Cheers (Drink To That)'.

"Just remembered dancing in a mosh pit w/ @katyperry to 'WE FOUND LOVE' lastnight!!!" Rihanna said on her official Twitter page.

"Haaa...well this morning actually."

The pair hit up an exclusive Rio De Janeiro nightclub where they danced to Rihanna's new single ahead of performing at the big Rio gig.

"@rihanna throwin bows' whilst finding love in a hopeless place, no doubt," Katy Perry replied, quoting lyrics from the new Rihanna single.

"@katyperry I love you!" Rihanna added.

"Had a blast 2nt, missed kickin it witcho CRAY azz."

Both Katy Perry and Rihanna have been busy performing all over the world so the mates squeezed in the valuable time in Brazil ahead of their tours hitting the UK.

Rihanna's new single 'We Found Love' featuring Calvin Harris will be available to buy and download next month.
