Movie star Robert Downey Jr. and his wife Susan Levin, who happens to be a Hollywood producer, are one of Hollywood’s favorite longest-lasting couples. They met on the set of the thriller Gothika in 2003 and started dating almost immediately, despite the ongoing divorce process with Robert`s first wife. Since then they have been together for 16 years. The photo above shows the newlyweds in 2005, a couple of months after their wedding.
