Lindsay Lohan and Dina Lohan Fight; Police Rush to Break Up "Violent Altercation"

In shocking and yet not-at-all shocking news, Lindsay Lohan and mom Dina Lohan were involved in a blowout, violent altercation early this morning, according to TMZ.
So bad it ended in a 911 call. Unreal.

Lindsay and Dina Lohan went to a nightclub in New York City last night, staying out until 4 a.m. before heading home to mom's home on Long Island.
Who the hell goes clubbing with their mom until 4 a.m.?
