Sienna Miller AND Kevin Costner Are Blonde for All the "Horizon" Events in Cannes

Regular readers of Drinks With Broads are only too aware that Horizon is Kevin Costner's passion project which may or may not have caused him to quit Yellowstone in a huff. What none of us were aware of -- as far as I know? Perhaps you are Costner's agent! Hello! -- is that he has, in the manner of many a person undergoing two divorces at once, gone blond. I do not know that it works. Dive in and see for yourself -- and what everyone (Julianne Moore! Michelle Yeoh! Sienna herself! Orphan!) wrote to this premiere. (So far, reviews have been mixed to bad -- not great news for Kev, who plans THREE!!! sequels.)
