The Love The Way You Lie singer said she wants to collaborate with Perry after the pair recently bonded.
'We just clicked. We have similar personalities and a similar sense of humour and from there she just seemed like a really down to earth person,' Rihanna told Entertainment Today.
'In this industry you don't meet a lot of people that are genuine, but Katy is such a free spirit, she has no edit button! We want to get in the studio and hopefully make something for this album, who knows - or maybe for her re-release. We want to do something together for sure.'
Talking about her friend’s impending marriage to comedian Russell Brand, she added: 'Well, I'm going, and it's in India and I'm excited about that because I've never been there. I'm just excited to see her get married. I can't wait to see her dress. She won't tell me what it is!'
