2) Brad Pitt and Angelina Jolie
The sexual tension in Mr. and Mrs. Smith was undeniable. But there was the huge glaring fact that Brad was married at the time, and the couple denied any romantic link. Viewers of the movies, the awards shows, and pretty much anyone who saw the two together were not convinced. Sadly, Brad’s marriage did end that year. They later admitted to falling in love on the set of the film, but still denied an actual affair. The couple have been together since 2006 and have had 6 children together, so they are working daily on their happily ever after.
