Madonna Madonna The dust has barely settled from her divorce announcement.

But don't think Madonna is sitting around mopping up her tears...

Not in the public eye, at least.

On the back of confirming her and Guy Ritchie's marital breakdown, Madonna put in a defiant appearance on her Sweet and Sticky tour in Boston.

In what some commentators took to be a dig at Guy, a scantily clad Madge introduced a song to her 20,000 fans by saying:

"That's right. I'm not sorry. This song is for the emotionally retarded. You might know a few people who fall into that category - God knows, I do."

The Sun report that following her performance, Madonna then threw a "divorce party" with her entourage at the Ritz Carlton in Boston.

A source told the newspaper: "Staff were joking that she was toasting her divorce. She seemed on a high after her concert."

Well, good to see she's not one to mourn the past, eh?
