Pattinson and Stewart are in Vancouver for the filming of Eclipse (the third installment in the Twilight saga), and the hot new couple is spending most of their time together at Rob Pattinson’s room in the Sheraton Vancouver Wall Centre.

“They’re hiding out at the Sheraton, while most of the cast is over at the nearby Sutton Place Hotel – they have separate rooms booked but are spending pretty much every night together in Rob’s suite,” a set insider told OK!. “When they’re not working, they’re mainly locked away with a ‘Do Not Disturb’ sign on the door. When you see them, the both look like they can’t stop smiling. It’s so adorable.”

For many of us, the public revelations concerning their relationship seemed inevitable. Despite the fact that Kristen Stewart used to be involved with Michael Angarano, 21, it seemed to many movie-goers and pundits alike that the real man for Kristen was the tall, well-spoken Brit, Pattinson. It just took some time for things to work themselves out.

“So it was unrequited love,” a friend of the couple said. “But their passion is so intense – all this sexual tension has been building for over a year. Everyone in the world was dying for them to get together.”

The two spent the summer apart, working on different projects. But as the old saying goes, absence makes the heart grow fonder. When the two re-united at Comic Con, the old sparks flew immediately.

“From the moment of their first embrace, it was clear the romance was going to pick up right where it left off,” an insider said. “Rob always thought Kris was gorgeous, but when he saw her in San Diego, he was blown away. The young girl he left behind in June had blossomed into a sexy rocker goddess.”

On August 15 the couple finally went public, enjoying time together at a Kings of Leon concert.

“They weren’t shy about cuddling up and kissing,” a source said. “They looked so happy and they were having a blast.”

Of course people working for the film are happy about the romance. For now.

“They can’t wait to see Rob and Kristen reunited on film,” said another insider. “Everyone’s sure they’ll set their scenes on fire.”

Filming for Eclipse is set to wrap up around Halloween. New Moon’s premier is set for November 20. At this point, insiders expect that Kristen Stewart and Robert Pattinson will move to make their living arrangements more permanent.

“They love the thrill of being under the same roof,” the insider said. “The fun they’ve had since getting back together has made them realize how much they care about each other. They’re really commited to this relationship and determined to give it their best shot.”

The big question is how the romance will affect the movie-going public. Do fans prefer Pattinson single? Is this a case of life imitating art or is it the real deal for two of Hollywood’s hottest young stars?
