Katy Perry will no longer attend the People's Choice Awards, due to take place in Hollywood tomorrow night.

In the wake of her split from Russell Brand, the singer has decided to cancel her planned appearance.

Katy tweeted: 'Unfortunately I will not be able to attend the People's Choice Awards. I want to thank u all for voting for me, fingers crossed! #KATYCATS'

Katy, 27, is up for seven awards at the ceremony, including Favourite Female Artist, Favourite Pop artist and Favourite song of the year.

It would have been her first public appearance since Russell filed for divorce on December 30, ending their 14-month marriage.
