As we first reported, Kate filed a report with the Southampton Town Police on Monday claiming Michael physically attacked her during an argument earlier that day.

On Wednesday -- the day this photo was shot -- Kate obtained a restraining order against Michael.

Michael says Kate's claims are all untrue.
