Katy Perry has revealed that some shows on her California Dreams tour were really hard to perform, as she was going through her split with Russell Brand.
In a new interview with The Hollywood Reporter, Katy said:
"There were times when what was going on in my personal life was so overwhelming that I had to bend over to let those tears fall straight out of my eyes and not my false lashes just as I'm about to go up on that ramp and sing 'Teenage Dream'.
"I had to smack myself across the face and say, 'These problems are my problems, they are not my audience’s problems, learn to separate that.'"
Her summer movie Part Of Me 3D will document some of the fallout, but she admitted:
"Nobody knows what really happened except the two people who are in it."
