M.I.A. and Rihanna

Rihanna and M.I.A. Link Up at ‘Watch the Throne’ Tour

Here comes trouble. Rihanna met up with fellow bad girl M.I.A. backstage at Jay-Z and Kanye West’s “Watch the Throne” tour at the O2 Arena in London on Sunday night. RiRi joined the hip-hop duo onstage for “All of the Lights” and “Run This Town,” while M.I.A. watched from the audience.

“Bad girls do it well,” tweeted the pop starlet, who won Top Streaming Artist at the Billboard Music Awards.

M.I.A. is readying the remix to “Bad Girls” with Missy Elliott, Azealia Banks, and Rye Rye. Is it too late to add one more to that list?
