They fell out last year when the 28-year-old Perry disapproved of Rihanna getting back together with rapper Chris Brown, reported Sun Online.

"Katy and Rihanna have both done the Hawaii and Cabo-type trips to Mexico before, so this time they're thinking something a bit different, like a safari in Africa.

They want somewhere where they can have amazing experiences but still get drunk," said a source.
