Robert Pattinson and Kristen Stewart’s reunion will likely be short lived, an insider tells RadarOnline.com. Close friends of the Twilight stars allegedly believe they will split again soon because Pattinson will be unable to get over Stewart's fling with director Rupert Sanders.
"Kristen and Rob's friends absolutely don't believe that this reconciliation is going to last," the source tells Radar. "Rob believes that Kristen didn't sleep with Rupert Sanders, but the fact is, she still cheated on him.”
“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,” the source adds.
Stewart, 22, and Pattinson, 26, reportedly had a “dramatic makeup” earlier this month. Stewart is also said to have moved back into the L.A. home they shared before her cheating confession in July. They will soon begin promoting the final Twilight installment, Breaking Dawn Part 2. The film is set to hit theaters on November 16.
