In Hollywood, it seems that everyone dates everyone and relationships start and end as quickly as people change underwear. But the best Hollywood relationships, even if they don’t last, are the ones that nobody knew about. The ones that you share with friends that get the, “WHAAAAAT!? I didn’t know that, girl!” response. But let’s be clear: there’s a difference between simply dating in Hollywood, and claiming one another in a relationship. There have been a flurry of both of those kinds of correspondences that started quietly and ended just as quiescent, and here are just a few we thought you might be nosey enough to want to know.

And if you did know some of them, that’s all good and dandy too. But either way, enjoy!

Jay-Z and Rosario Dawson

Before he really got serious with Beyoncé and was a household name, and supposedly after an alleged short boo-ship with the late Aaliyah, Jay-Z was romantically involved with actress Rosario Dawson. You know Rosario, she was the actress in movies like Kids, He Got Game, Sin City and a lot more. Their relationship…or time together doing whatever it was they were doing…occurred in 2000, and people even assumed that the second verse in the song “Lost Ones” was about Dawson (that was until Jay set the record straight in Decoded, saying the song was about Bey). But it didn’t last long.  Jay went on to date Beyoncé and Rosario, at the time, went on to date “Sex and the City” hunk Jason Lewis (who played Kim Cattrall’s young actor boo). No offense to Jigga, but what an upgrade!
