WOWZA! Jennifer Tilly's still got it! The 66-year-old Real Housewives of Beverly Hills star just went COMPLETELY naked on Instagram! In a new post uploaded on Monday that she captioned "thirst trap," the reality star can be seen covering her chest with her forearms, while standing nude in an in-ground pool. The water only goes up to her hips, leaving very little to the imagination. She's donning a fiery red lip with some round sunglasses and a flower in her hair.
