Lindsay Lohan and her mother got in a fight

Around 4am last night/this morning, Lilo and her mom Dina got in a physical fight on their way home from going clubbing.  What did they fight about?  Whether or not their cab should go back to their home in Long Island or to a hotel.  Dina called the cops on her daughter and supposedly there was blood.  My only question is - who goes clubbing with their mom?
