Keeping up with who’s in and who’s out in Katy Perry’s friendship circle is exhausting work.
It can be especially baffling if your name is Rihanna and actress Katy, 34, is having a hen do.
One minute you are besties, the next you’re blacklisted.
The hot pop singer, 31, organised Katy’s hen do when she was marrying Russell Brand in 2010.
Then the Firework star could not get enough of the Bajan babe.
Katy wanted her to strip at the bash and gushed: “She’s hot, I love her. She’s just the coolest chick.”
But this time, as the I Kissed a Girl singer prepares to marry Hollywood hunk Orlando Bloom, 42, Rihanna does not even make the guest list.
Instead Ms Perry has roped in Big Little Lies actor Shailene Woodley, 27, to arrange the party.
Invites have been extended to celebs such as singer Ellie Goulding, 32, and US actor Anna Kendrick, 34.
Katy was a guest at Ellie’s wedding a fortnight ago.
My source says: “It’s nearly a decade since Katy’s marriage to Russell and so much has changed in that time.
"For her first hen, Rihanna was so involved, she put a lot of it together, now they never speak.
"There's no friendship between them. It’s pretty sad. But Katy has found a new circle of friends.”
The source of Katy and Riri's feud remains a mystery although it does date from when the former started dating Pirates of the Caribbean star in 2016 and Rihanna distanced herself.
Since then Katy has kissed and made up with former arch nemesis Taylor Swift.
Maybe she could do the same with Rihanna.
