MIA has reportedly said sorry to Madonna over the furore surrounding her middle-finger gesture during the Queen of Pop's Super Bowl halftime show on Sunday (February 5).

The 'Paper Planes' hitmaker "flipped the bird" during her "I don't give a s***" line, seconds before the camera cut away from her.

A source told The Sun: "She wasn't thinking. She was caught in the moment and she's incredibly sorry."

It was reported earlier in the week that Madonna was unhappy with her 'Give Me All Your Luvin'' collaborator, with an insider saying: "M.I.A did nothing similar in rehearsals. Nobody knew she was going to pull this stunt.

"Madonna wanted to put on a world-beating performance. But everyone ended up talking about this girl's middle finger."

MIA, who is usually a frequent Twitter user, has not taken to her micro-blogging account since the infamous performance.
