The 'California Gurls' singer says the final performance of her extensive tour is likely to be emotional for her.
Katy Perry has admitted she may tear up on stage tonight for the 122nd and final date on her 'California Dreams' tour.
The 'Teenage Dream' singer will perform a free home state show this evening (23rd November) at the Staples Centre in Los Angeles and has warned fans she is likely to be emotional.
"Tonight & tomorrow I'm giving THANKS," Katy tweeted. "Also I'm gonna try & keep it together but don't judge me if I cry like a baby on stage #endoftourblues"
Yesterday Katy admitted it felt right to be rounding off the mammoth tour with a concert in California, close to her home city of Santa Barbara.
"Can't believe I'm playing Staples tomorrow. #TheCaliforniaDreamsTour comes home. Show 121."
Katy was recently forced to deny rumours she is expecting her first child with husband Russell Brand, after being heard telling friends at the American Music Awards she is ready to settle down.
