Heather Mills Goes Nuts on Photog

Heather Mills has had quite enough, thank you, of the paparazzi stalking her every move -- and she finally hit her cracking point yesterday.

Paul McCartney's estranged wife went crazy on a photographer in London yesterday by screaming and yelling -- even going so far as to kick the cameraman -- all while videotaping the incident herself!

It's not clear what set the former model off balance, but her freakout might land her in yet another lawsuit. Rumors have it that she and Paul are close to a $50 million settlement in their nasty split.
