Katy Perry kicked off her California Dreams Tour last night in Portugal giving a rousing performance of all her greatest hits.

She hid any signs of sadness of missing her husband Russell Brand who she will be away from her for long periods of time while she is travelling around the globe.
The I Kissed a Girl hit-maker paraded on stage with her dancers at the Campo Pequeno arena in Lisbon at the start of her nine-month world tour.

Katy's entire stage was inspired by all things sweet with a candy cane staircase and big bright lollipops as her backdrop.

She even tweeted that she is getting into the theme by eating fresh cotton candy as her pre-show ritual snack.
