M.I.A.

From fighting racism, battling sexism, or advocating against war, pop music can be used for more than just getting people out on the dance floor.

The electro-rap queen and dubstep king are teaming up on 'Matahdatah.'

The M.I.A.-directed clip for "Swords" and "Warriors" co-stars the fiercest band of sword-wielding girls we've ever seen.

We compiled a gallery of celebrities who are probably much older than you think.

Controversial rapper M.I.A. has revealed that the NFL is trying to shake her down for $16.6 million as a result of her one-finger salute, in which she flashed her middle finger at the camera (and for all the world to see) while performing as part of Madonna's Super Bowl Halftime Performance in 2012.

There never seems to be a dull moment in the life of M.I.A. She is currently embroiled in some legal trouble after threatening to take her son Ikhyd out of the U.S. and back to London.

Lily Allen -- is anyone calling her Lily Rose Cooper? -- returned to performing and in an unusual 'fashion,' literally. The singer, who had retired from music and just birthed her second daughter, Marnie, hit the stage at a raunchy lingerie fashion show in Paris (Feb. 26).

Congrats to One Direction, Lana Del Rey and Frank Ocean! Each was honored with a U.K. Music Video Award.

While rap may have started out as a mostly male-dominated genre, the ladies who have been successful in the rap game over the years are just as good at spitting hard and fast rhymes as their guy counterparts. But out of newer rhymestresses like Nicki Minaj and M.I.A. and legendary names like Missy Elliott and Lauryn Hill, who gets your vote for the best female rapper?

M.I.A. has teamed up with Madonna and William Orbit on a new song called 'Baby,' which leaked online on Monday (July 9).
