Biggest Headline of 2009: Are Rob and Kristen Dating?

It's December, which means it's time for PopSugar Network's Best of 2009 coverage! Along with polls and slideshows, we'll be bringing you PopSugar's biggest headlines of the year.

It was the biggest are-they-or-aren't they question of the year — are Robert Pattinson and Kristen Stewart dating in real life? In the run-up to New Moon's release, it seemed like everyone was speculating about whether or not Kristen and Rob acted like Bella Swan and Edward Cullen offscreen. We got to see Robert and Kristen as they wrapped up promotion of Twilight earlier this year and as they headed to Vancouver to film New Moon in the Spring. During breaks from the set, the duo shared nights out together and even shared cab rides home. They were soon off to Italy, where it was time to film their passionate scene with a hot shirtless Rob. Once that movie wrapped, it was time to make the awards show rounds for Twilight. Robert and Kristen made a memorable appearance at the MTV Movie Awards, where they showed off their obvious chemistry while accepting the Best Kiss honor before evidently spending that night together.

The duo split up for a good chunk of the Summer, as she stayed in LA to work on The Runaways and Robert headed east to film Remember Me. They reunited at Comic Con before the Teen Choice Awards and the VMAs, where they looked too cute together backstage. Soon they were off to Vancouver for Eclipse, kicking things off with a Kings of Leon show before filming began — Robert and Kristen also raised a few eyebrows by looking extremely close throughout the show. The work never stopped for Robert and Kristen because after finishing up on Eclipse they were off to promote New Moon with cozy-looking stops across the globe. Soon, everyone from Jennie Garth to Catherine Hardwicke were weighing in on their situation. The evening Robert and Kristen were spotted holding hands at Heathrow didn't do much to cool speculation that the duo was together — and, conveniently, all the wondering likely helped make their film a hit. Robert and Kristen don't seem to be leaving each other's sides anytime soon, as they were just spotted arriving at LAX together before Thanksgiving.
