Katy Perry, Rihanna plan African vacation

Singers Katy Perry and Rihanna are reportedly back being friends and are even planning to holiday together in Africa.

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.
