David Gest slapped Liza Minnelli with a $10 million lawsuit Tuesday, claiming his estranged wife repeatedly beat him during alcohol-fueled rages — causing neurological damage and headaches (not to mention one scary mug). Gest — who says he must take 11 prescription medications a day to manage the pain — alleges that Minnelli took on superhuman strength when she was drunk, making it difficult to for him to defend himself in the absence of kryptonite. The couple separated in July, just 16 months after their star-studded nuptials. Minnelli's camp had no comment on the suit.
