Tom Cruise v Brooke Shields
In a bizarre public diss, Scientology-loving Tom Cruise attacked Shields for her use of drugs to combat a severe bout of post-natal depression, saying instead that she should have turned to "vitamins and exercise". In other words, a treatment more in line with his personal beliefs.
Brooke swiftly responded in a piece for the New York Times not long after his statement, saying: "I'm going to take a wild guess and say that Mr Cruise has never suffered from postnatal depression."
