7. Rihanna and Katy Perry
Gruesome twosome Katy Perry and Rihanna stick together through thick and thin, and it's claimed that Rihanna was the first person Katy Perry called when she broke up with Russell Brand after 14 months of marriage. A source told The Sun: 'Katy is hardly speaking to anyone right now, but she called Rihanna as soon as she heard Russell was filing for divorce. Katy was embarrassed about calling her parents as they'd been so against Russell in the first place, but Rihanna was a great support for her.
