Katy Perry is being supported by Rihanna following the breakdown of her marriage.
The Firework hitmaker - who spent the festive period in Hawaii with friends - has shared a number of heart-to-heart phone calls with her pal as she deals with her split from British comic Russell Brand after 14 months of marriage and the We Found Love singer has been a "great support" in helping her cope.
A source told The Sun newspaper: "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 and she really helped to calm her down."
Rihanna is now said to be planning a holiday to Mexico with Katy to help her get over Russell.
