While there's been a long-held theory that Rihanna and M.I.A. might have some sort of issue with each other over RiRi's "Rude Boy" video (which appeared to take some of its creative influence from M.I.A.'s video for "Boyz," released three years prior), there doesn't seem to be much beef between the two.

They got together for a few photos last night, at the O2 Arena in London, where they were both taking in the Watch The Throne concert. There, Rihanna joined Kanye and Jay-Z on stage to perform "All of the Lights" and "Run This Town," while M.I.A. watched from the audience. Still, it's nice to see them together.

"Bad girls do it well," Rihanna captioned with one of the photos. Indeed, they do.
