Katy Perry & Rihanna Prove They're Worthy To 'Rock In Rio'

By Michael Lopez

If you wondering why Katy Perry and Rihanna were chosen to open Brazil's massive Rock In Rio festival, here's your answer. Latina or not, they can put on a dynamite show and literally get a crowd of over 100,000 chanting their names. Both ladies did not disappoint on kickoff night, blasting into some very provocative performances.

After Rock In Rio's traditional fireworks commencement, Katy made her big entrance against fairy pink lighting. She had previously tweeted plenty of hyped-up messages to her fans and bootlegged versions of her performance have already leaked on YouTube.

'I'M READY TO ROCK RIO!” she posted before taking the stage. "100,000 people tonight! I LOVE YOU BRAZIL... You've waited so long for me so tonight I'm gonna give it to you!!"

Her first song, "Teenage Dream," has proven to be a huge hit in Brazil. And she sang it in a Carnival-inspired costume, complete with peacock feathers in the backside. From there, it was on to "California Gurls," "I Kissed A Girl," and all of the famous Perry hits you know and love.

Rihanna took the stage shortly thereafter and didn’t seem intimidated one bit by Katy’s massive applause. Of course, these two ladies happen to be best friends, which Ri Ri emphasized in a tweet to her fellow headliner.

"@katyperry I love you! Had a blast 2nt," she posted.

Rihanna made sure her fashion choice got a lot of attention too. In between hits like "What’s My Name?" and "Umbrella," the 23-year-old singer showed off quite a bit of skin in a very revealing striped mini dress!

But unfortunately Rio wasn't all fun and games over the weekend. Reports came in Sunday morning about a gang of masked gunmen who robbed nearly 20 concertgoers. The men are still at large and officials are advising all Rock In Rio attendees to keep a close eye on their valuables throughout the remainder of the festival.
