Several sources have confirmed that Robert Pattinson and Kristen Stewart are definitely back together … which is pretty damn convenient because the next “Twilight” movie comes out next month.

As you all may know, human girl K-Stew cheated on her vampire boyfriend R-Pattz earlier this year with her “Snow White and the Huntsman” director Rupert Sanders (who is also a human) … and it was all captured in a series of photographs that were published in magazines and all over the Internet this past July.

When her cover was blown, Kristen released a public statement apologizing for being a trampire, but even that wasn’t enough to get her vampire boyfriend to come back to her.

Now, following recent reports that they have moved back in together, an anonymous source is telling People that their relationship is back on all the way, and Rob has decided not to sell the Los Angeles love nest he once shared with his previously pure and innocent human girlfriend.

Whether they’re together for real, or just to promote the next (and final) “Twilight” movie remains to be seen, seeing as they are legally required to at least be cordial enough to make it look like they care about each other in upcoming promo appearances.

“Rob and Kristen are legally required to promote Breaking Dawn Part 2 together along with the rest of the cast,” a source close to the situation told Radar Online.

“Their individual contracts have very specific language about what is legally required of Rob and Kristen to do on the publicity tour.

“The studio execs at Summit weren’t happy when Rob and Kristen broke up, but this is why there are clauses about what is required of the stars to do.”

“The Twilight Saga: Breaking Dawn – Part 2” hits theaters worldwide, starting on Wednesday, November 14th. Rob and Kristen’s first promo appearances kick off this month.
