Erin Muller says Michael Lohan is a vagina kicker!

This may get complicated so bear with us. 

Michael Lohan was arrested Monday for violating a previously filed restraining order to keep him away from from his ex-girlfriend Erin Muller, who looks eerily like his daughter, Lindsay Lohan

Now Erin wants those charges dropped and she alleges that he physically abused her about a dozen times over the last two years. One time, he even kicked her "in the vagina."

Keep in mind on Dec. 17, Lohan  filed a complaint claiming Erin kicked him in the head when he tried to pull her out of the car because she was too "drunk and high" to drive.
