Madonna/Guy Ritchie divorce already heating up

No divorce papers have been filed yet, but the gloves are already coming off between Madonna and her still-husband-by-law Guy Ritchie, and Madge is throwing the first punches.

While performing in Boston on Wednesday night, Madonna apparently dedicated a song to Guy, telling the crowd that the song goes out to "anyone who's ever had to deal with someone who is emotionally retarded." She also called her marriage a three-ring circus.

Wow, sounds like the past few married years for her haven't been a fun night at the ballpark (get the A-Rod/baseball reference? I knew you would.)
