Hollywood celebrity couples have always met up at one movie or television series before their romance bloomed off-screen. The "Robsten" duo may be the most popular nowadays but before them came the "Brangelina" duo and a few more others.

The famous "Robsten" duo came to be from the film adaptation of Stephanie Meyer's best-selling novels, "Twilight." British actor, Robert Pattinson played the brooding, sparkly vampire, Edward Cullen who fell in love with the awkward girl, Isabella Swan played by American actress, Kristen Stewart. It didn't take long for the onscreen couple to fall helplessly head over heels for each other as soon as the cameras stopped rolling.

Another vampire couple that swooned hearts onscreen is HBOs original series, "True Blood". Anna Paquin falls desperately in love with Stehen Moyer's vampire persona onscreen and despite the epic age difference - the two hooked up and married right after the series.

The same thing goes for "Vampire Diaries'" Ian Somerhalder and Nina Dobrev. Though their characters portray a love-hate relationship, Ian and Nina hooked up easily after the first season of the highly acclaimed television series. Their age difference however is just a little bit on the line of a five year gap in comparison to Anna Paquin and Stephen Moyer's age difference.

Taking off the vampire theme and moving on to superhuman powers is "The Amazing Spiderman's" Andrew Garfield who hooked up with co-star, Emma Stone. Another superhero who couldn't move on from his leading lady onscreen is "Green Lantern's'" Ryan Reynolds who pursued "Gossip Girl's'" Blake Lively.

Nicholas Hoult may be the "Beast" in "X-Men: First Class" but that did not stop "Hunger Games'" Jennifer Lawrence to fall head over feet for the British actor. By the looks of their innumerable dates from surfing to basketball, these two enjoy a physically fit relationship.

The "Brangelina" duo continues to being the most popular couple after their box-office film, "Mr. & Mrs. Smith." Though Angelina Jolie and Brad Pitt are yet to tie the knot, Jolie has a bunch of lovable and charming kids.

A couple who have tied the knot after their onscreen relationship would be "Step Up's" Channing Tatum and Jenna Dewan. These two have been together in spite of a few Hollywood splits and controversies which pretty much prove what they had onscreen was the real thing.

With an on-off and on again relationship, it's surprising to see that "The Last Song's'" Miley Cyrus and Liam Hemsworth are still together. News is, the two are now stronger than ever and Liam continues to be a supportive boyfriend to Miley especially during those paparazzi days that revolved around the controversy of her "smoking too much weed."

Lastly, after being together for how many "Glee"-full seasons, Cory Monteith and Lea Michelle have finally hit off and are together for real. Though it has sparked a few rumors that it's a publicity stunt, Lea and Cory have been spotted enjoying each other's company that is enough to say it is not all for show.
