While they hadn't been dating long enough for most people to likely even realize they were a couple, one of the greatest comic book culture hook-ups ever has ended. The entertainment world was captivated when it was revealed that Man Of Steel's Henry Cavill was dating The Big Bang Theory's Kaley Cuoco. However, EOnline is reporting that sources have told them that Henry Cavill and Kaley Cuoco have split up. During their two week courtship, paparazzi photographed the pair hiking together and holding hands. Kaley Cuco even tweeted, ""Everyone go see 'man of steel'. It's fantastic in every single way." There's no information on exactly what went wrong. Perhaps, Kaley Cuoco had a change of heard over what the Man Of Steel did to Zod or maybe she was upset by Superman's actions in Justice League #22. However, EOnline does note that the couple is remaining friends.
