Video: Rihanna Gives Surprise Performance at Jay-Z and Kanye West's Watch the Throne Tour

Rihanna has apparently got the honor to share the stage with Jay-Z and Kanye West on one of their recent shows in London, England. Coming to the O2 Arena to watch the rappers' Watch the Throne tour on Saturday, May 19, the "We Found Love" hitmaker ended up being a surprise guest for the night.

While she's not featured in Jigga and Yeezy's collaborative album "Watch the Throne", the 24-year-old songstress took the stage to help the pair in singing two songs. Wearing a cropped black top, skinny jeans and a beanie, she performed "All of the Lights" with Yeezy and joined Jigga in his "Run This Town" set.

After the show, Riri shared her excitement to her 19 million-plus followers on Twitter. "#RihannaNAVi made historih tonight as the first person to Watch The Throne AND join it!!! No one is allowed on that stage! Thank u guys," so she declared on a tweet. She also posted a backstage photo of herself with a caption, "WTT tour #London."

Jigga and Yeezy will head off to Switzerland on Thursday, May 24 for a performance at Zurich Hallenstadion. They are also set to play in other European countries, including Denmark, Sweden, France, Belgium and Germany, until mid-June. The U.S. leg of their tour will be kicked off October 28 in Atlanta, GA.
