Rihanna's London fans may be her favorite. Not only does she ride the subway with them, but the record-shattering superstar performed 'We Found Love' live for the first time ever Monday night (Nov. 14) at the O2 Arena!

RiRi closed her concert with the Calvin Harris club banger following 'Umbrella.' During the song, blasts of confetti flew into the crowd, creating a party vibe that would probably displease her doctors. Rihanna showcased a lot of moves from the 'We Found Love' video's farm scene onstage, dancing so hard that at times she could barely muster breath to sing her lyrics. We bet her Swedish fans are jealous!

Rihanna's star is huge in the states, but it may be even brighter across the pond. She's scheduled to headline London's Jingle Ball and next year's Wireless Festival.

Not only does Rihanna dig the U.K., but she also likes its imports. She's slated to perform on the American 'X-Factor' this Thursday, Nov. 17. Perhaps her stateside fans are next to find love with her live!
