Singing 'Only Girl (In the World)', 'Big Pimpin' ' and 'Whip My Hair', Katy Perry wished Rihanna a 'Happy Birthday' during her tour opener in Portugal.
Katy Perry kicked off her California Dreams tour at the Campo Pequeno Arena in Lisbon, Portugal on February 20. She performed around 20 songs during the Sunday night concert, singing her own tracks like "Teenage Dream" and covering other artists' songs.
In one acoustic set, the 26-year-old singer/songwriter performed a rendition of Rihanna's single. Wearing one-shoulder dress, she sat on a candy-cane stool and sang "Only Girl (In the World)" before ending it with a shout-out to her BFF. "Happy Birthday Rihanna," she shouted.
RiRi turned 23 that night. "@rihanna happy birthday boo. Wish I could b there to blackout! Luv U!" Katy tweeted to the birthday girl who's celebrating the big day in her Beverly Hills house. Replying her post, RiRi wrote, "Are u kidding? I missed ur WEDDING!! This is small stuff boo! #whenworkcalls."
Beside singing Rihanna's 2011 Grammy Best Dance Recording, Katy also covered Jay-Z's single "Big Pimpin' " and Willow Smith's fun song "Whip My Hair". During the medley performance, she managed to play a bedazzled flute.
The stage for the tour was set as a dreamland with a candy-cane staircase and big bright lollipops as the backdrop. She herself underwent various costume changes including a pink tutu dress with a candy striped bodice and red heart neckline. The concert began with a short story played on three giant screens. It reportedly revolves around her, the daughter of a butcher, who falls in love with the son of a cupcake baker. She then falls asleep into a dream, and that's how the California Dreams tour is born.
