It looks like Robert Pattinson and Kristen Stewart are back together. 

While earlier this month, it was rumored that they moved back in together, a source confirmed to Perez Hilton on Wednesday, "They are living together and have reconciled. [But] he's extra sensitive right now and insecure."

Pattinson moved out of the Los Angeles home they shared earlier this summer, after finding out that Stewart cheated on him with Rupert Sanders, the director of her film, "Snow White and the Huntman."

A source told the celebrity news blogger that "They pretty much decided they couldn't live without each other. Kristen poured her heart out to Robert and told him it was a one-off and a mistake. Rob sees it as Kristen made a really stupid mistake. After a lot of long tearful talks, they've worked it out. Rob can see how truly sorry Kristen is and has totally forgiven her. They really do love each other. For now they are focusing on themselves."

According to reports, Stewart has one month to see if they can make the relationship work.

"He has warned Kristen that he might never be able to forgive and forget. But he's agreed to give it a month to see if they can make it work. If they can't, he says he will walk away. Kristen hasn't stayed over at Robert's new place yet. They have seen each other most days since their initial meeting, but they are taking baby steps. He has also requested that they don't talk about Rupert or what happened. She has nobody to talk to because Robert has made it clear the topic is off-limits," a source told Grazia magazine.

This is great news for fans who plan to attend the Los Angeles red carpet premiere of "Twilight Saga: Breaking Dawn - Part 2" later this year.
