My trouble with Madonna's accent is that it began seemingly overnight after moving to London. It feels like she changed her accent for the same reasons she changes her hair - to get attention and manipulate the public. She simply rubs me the wrong way.

Don't get me wrong, I think everyone adapts their speech(intentionally or not) when surrounded by people with an different accent. Hers, however seems to me a bit of a con job.
