M.I.A. Will Soon Be M.I.A.?

Word on the street is that one of my fave artists, M.I.A., is retiring. She performed at the Bonnaroo music festival in Tennessee over the weekend and announced (several times) that she was retiring.
Apparently, M.I.A. told the crowd "This is my last show."
“Thanks for coming to my last gig,” she told the audience before she left. Source
If this is true it would make me very sad inside.
