With the show about to start its 10th season, rumor has it that the on-screen couple might be getting back together in real-life, but we'll have to see about that.

Elena Gilbert may have struggled in choosing between the Salvatore brothers on The Vampire Diaries, but for three years, Dobrev was team Somerhalder all the way.

Taking a cue from their on-screen characters, the Gossip Girl costars' relationship heated up in real life, with Lively and Badgley dating for a solid three years while working together, too. Their romance ended in 2010, which must've made it super strange to not only continue working together but also to marry each other on the show during the final, 2012 season.

Keaton and Pacino had a two decades-long on-again, off-again love affair during the '70s and '80s while starring together in the iconic Godfather trilogy.

While the story of Dawson and Joey was unfolding, another love story was in the works behind the scenes. Holmes and Jackson had a somewhat under-the-radar but serious relationship while filming Dawson's Creek during the late 1990s. While the relationship was short-lived, the stars continued working together until the show ended in 2009. (And in our minds, it'll always be Joey + Pacey forever.)
