Mr. Big is switching sides?! With the feud between Kim Cattrall and Sarah Jessica Parker still going strong, a Sex & the City star who was always on SJP's side has seemingly changed his mind! This feud has been going on for YEARS, as Perezcious readers know. And with Big himself - AKA Chris Noth - previously defending the Carrie Bradshaw portrayer, we were surprised to see him suddenly so chill with Kim! On Instagram Thursday, the Samantha Jones portrayer showed off her 69th birthday celebrations in style, with a glass of champagne and a Moon Mammoths hat.
