Lohan was charged by the Southhampton Police Department, and will be formally arraigned on August 18. At that time, he's expected to enter a plea to the charge.

On Wednesday, Lohan denied Kate's abuse claims to Breaking Celebrity News, saying while they did have an argument before he left for L.A., he never laid a hand on her.

As Breaking Celebrity News reported, Major, 27, has filed a restraining order against Lohan and it was granted. She claims Lohan shoved her and kicked her in the face while she was down.

The couple was set to be married at the end of the year at Oheaka Castle in New York.
