And although Twi-hards are delighted K-Patz are back together, their friends don't for one second think that the reunion will stand the test of time and that once promotion for The Twilight Saga: Breaking Dawn - Part 2 ends then Robert will end relations with Kristen for good because he will no longer have any work ties with her.
"Kristen and Rob's friends absolutely don't believe that this reconciliation is going to last," a source told RadarOnline.
"Rob believes that Kristen didn't sleep with Rupert Sanders, but the fact is, she still cheated on him.
"Rob's pals think it was easier for him to get back together with her right now because of the upcoming publicity blitz they are going to embark on to promote Breaking Dawn.
"Kristen definitely convinced Rob that this was going to be a bitter-sweet time for them, because this is the last Twilight movie. Kristen loves Rob, no question about it, but she just isn't as mature as he is. Rob's buddies would be stunned if the couple goes the distance.
Robert is said to have only forgiven Kristen because she convinced him that she did not actually have sex with the Snow White and the Huntsman filmmaker and that they just made out a few times.
The couple split around two months ago after pictures surfaced of Kristen and Rupert in an intimate embrace and the pair moved out of their $6 million home in Los Angeles but the actress continued to wear Rob's clothes in hope they got back together.
"Robert's friends just wish he could get Kristen out of his system," the insider added. "They are disgusted with her behavior and want nothing to do with her. Kristen has some type of hold on Rob though and he seems to be thoroughly addicted to all the drama because she is always sulking and brooding about something."
Weigh in below - do you think Rob and Kristen's relationship will last?
