Katy Perry launched her California Dreams tour in Lison, Portugal last night and while on stage she gave her bestie Rihanna a birthday shout. The shout out followed her singing "Only girl" (in the world) which was part of an acoustic mash up of songs, which included Jay-Z's "Big Pimpin" and Williow Smith's "Whip My Hair". I absolutely love Katty perry's spunk and creativity, I hope this part of the act makes it through the whole tour.
Check out some tweets between the besties today...
