The 'We Found Love' singer stayed close to her good friend during the Los Angeles ceremony on Sunday night.
Rihanna and Katy Perry were pictured smiling and enjoying each other's company as they hung out together during the Grammy Awards 2012 in Los Angeles on Sunday night (12th February).
The Bajan star and the American artist posed for pictures together and both wore eye catching and breathtaking outfits.
Rihanna showed off her svelte figure in a tight black open chested gown, while Katy, who had earlier arrived in a flowing blue dress, changed into a less flamboyant gold number.
The 'We Found Love' singer was one of the early winners at this year's event because of her collaboration with Kanye West on the song 'All Of The Lights'. Katy failed to take home any prizes at this year's ceremony.
