Just yesterday the two were reported to be buying a house together in Cornwall but now it has transpired that Kristen is failing to gain Robert's trust following their reconciliation.According to a source close to the couple, since getting back together Rob has struggled to fully trust Kristen again.Understandable considering she cheated on him with another man.The source said: "Kristen is working hard to try and force the relationship into what it was before."

"But the truth is, she's going to have to take it slowly with Robert because he's still having trouble trusting her again."The source added that Robert Pattinson is struggling the most with trying to forget Kristen Stewart with another man.They said: "For him to carry on like nothing happened is very hard."The insider added: "The problem is he can't forget her infidelity. Kristen claims that she never actually slept with Rupert Sanders, but Robert still has that nagging feeling of doubt that she did."

In 2009, Ryan Reynolds and Sandra Bullock took the stage at the MTV Movie Awards to present the Golden Popcorn for Best Kiss. In what would become an ongoing theme over the next few years, "Twilight" stars Robert Pattinson and Kristen Stewart won the prize.They took the stage to raucous applause and proceeded to tease a reenactment of their onscreen smooch without actually going ahead with the deed. After the pair won again the next year and finally puckered up for the crowd 2011 rolled around, and Ryan Reynolds was again picked to hand out the Best Kiss award, this time with "Green Lantern" co star Blake Lively. Thus both Ryan and Blake had quite a view when, after the Twi-kids once again nabbed the award, Pattinson bounded down from the stage, away from Stewart and into Taylor Lautner's arms for a seriously unexpected kiss."I did not know that there would be a 'Twilight' on 'Twilight' kiss," Reynolds told us days later when we caught up with him at a "Green Lantern" press event. "We had no idea."Of course, having witnessed the inaugural "Twilight" Best Kiss win, the actor had been imagining something of the sort for years. "I'd seen it in my head many times as I closed my eyes," Reynolds added. "But that was quite shocking, actually, that he would just run off the stage like that and attack that poor boy."Lively's family, for their part, were equally stunned by the smooch and the unwelcome attention of MTV's cameras. "My family was sitting behind them," Lively explained. "They were like, 'Ooooh!' They were hiding. They were so shy."

Robert Pattinson and Taylor Lautner The biggest moment of the night.Everyone was anticipating a liplock from Best Kiss winners Robert Pattinson and Kristen Stewart, since they fooled us last year. But instead, we got an even bigger surprise.And though the Harry Potter peeps were effectively shut down by Team Twilight, the night had some other fine moments, including a surprise appearance by Justin Bieber, Jim Carrey's crazy suit that flashed images of dogs humping among other things and Gary Busey in a big plastic bubble.

And in the show's other watercooler moment, Reese Witherspoon, winner of the Generation Award, revealed that she knows how to fire off some saucy jokes when she needs to. When Robert Pattinson spoke of how Witherspoon played his mother in his first movie and then now his lover in Water for Elephants, the actress came back with, "So Rob, the punchline of your joke is really that you're the best mother in Hollywood." 

"I get that it's cool to be bad. But it's also possible to make it in Hollywood without a reality show. It used to be that if you make a sex tape, you hide it under your bed. If you take naked pictures of yourself on a cell phone, hide your face."

Robert Pattinson and Kristen Stewart have been rehearsing in case they win the Best Kiss award at the MTV Movie Awards tonight,The Twilight duo, who have won Best Kiss at the MTV movies awards for two years running, are up for the smooch prize again this year. so as not to disappoint fans this year.And, while the anticipation of seeing these two actors kiss is huge among Twihards, Robert Pattinson and Kristen Stewart aren't known for being very good at pulling off a great lip locker.Witness try number one when RPattz and KStew won this honor. The kiss was faux, not much better than an air kiss like both of these thespians find themselves bestowing upon people they hardly know.they are forced to show the world they can do this in real life as well as they can on celluloid. About three hours time will tell whether their lips will smack on national TV or not. And that not only goes for the MTV Movie Awards acceptance, but also potentially for a PDA while these two sit in the audience waiting to know if they will be called upon to get up on stage for an actual reenactment in the spotlight, live at the Gibson Ampitheater in Los Angeles.
