Pop stars Lily Allen and Katy Perry dislike each other so much that they can't bear to be in the same place together, causing problems for event organisers who want to invite both of them.
Thesun.co.uk reports that the two singers were supposed to be at Chanel's spring-summer show recently. And the organisers had to work behind the scenes to ensure that the two don't bump into each other.
"Chanel did not want to risk offending Katy by not inviting her. Nor could they risk upsetting Lily if her rival popped up in the front row. Very senior people had to smooth things out so there was no embarrassing scene and Katy stayed away," a source said.
The two have been at odds with each other recently. Perry called Allen "fat" in an interview recently and Allen retaliated by accusing Perry of copying her.
