Dina and Michael Lohan have begun long-overdue divorce proceedings in a Long Island court. Outside the courtroom today, Dina's security dude Ty Dux talked shit about Michael, then Michael shot back by accusing Dux of being in cahoots with Dina's brother Paul Sullivan, whom Michael has accused of driving a wedge between himself and Lindsay (who remains blissfully far away from the nonsense, in rehab, happy as a clam).
