Perry was noticeable absent from Rihanna’s charity bash this week and the Umbrella star made a sly dig at her former ‘bestie’

She famously fell out with Taylor Swift and now poor Katy Perry’s friendship with her showbiz bestie Rihanna has become a tad frosty too.

The ladies have not been seen together for more than a year and have gone to extreme lengths to avoid each other at recent showbiz events.

Tellingly, Katy was absent from Rihanna’s Los Angeles Diamond Ball charity bash this week . And on the red carpet Rihanna made an astonishing dig at the woman she once described as “one of my best friends in the industry”.

When asked if she would join Katy on the new American Idol panel , she looked unimpressed before sniping: “I don’t know, it depends on how bored I am.”

Whispers about their apparent fall-out started going round when Katy was the only big name absent from Rihanna’s MET Gala Afterparty.

The Firework singer then spent Coachella fretting with pals about how her close friend seemed to be freezing her out. They spent the festival apart, with Rihanna snubbing Katy’s shoe launch.

A source said: “They didn’t have a big bust-up over one specific thing, but over time their friendship has gone from being one of the strongest to practically nonexistent. Katy was pretty gutted about it.

“Some pals have said they just grew apart when she started dating Orlando Bloom last year but the reality is, nobody knows exactly what went down between the pair.”

The girls were once so close that Rihanna attended Katy’s hen party ahead of her marriage to Russell Brand.
