Katy Perry kicked off her California Dreams world tour in Portugal last night (February 20) – and played a set including a trio of covers.

The singer played to a sold-out crowd at the Campo Pequeno in Lisbon.

As well as performing songs from her two albums 'One For The Boys' and 'Teenage Dream', Perry also performed a medley of covers.

Backed by an acoustic band, the singer played Rihanna's 'Only Girl (In The World)', 'Big Pimpin' by Jay-Z and Willow Smith's 'Whip My Hair'.

The first UK and Ireland leg of Perry's California Dreams tour is due to arrive in the UK next month.
