Speculation of a possible reconciliation between Kristen Stewart and Robert Pattinson has been swirling since the news broke that she cheated on him with director Rupert Sanders – and PEOPLE has learned that the couple did recently reunite.

Stewart, 22, and Pattinson, 26, met up in Los Angeles over the weekend of Sept. 15, PEOPLE reports in its upcoming issue.

And, according to an insider, the Twilight hunk's pals "think they'll be a couple again."

While Pattinson was completely heartbroken over the split, says another source, moving on is "easier said than done ... and clearly harder than expected."

When Stewart admitted to having a tryst with Sanders, she made clear she hoped it wouldn't spell the end of her three-year relationship with her Breaking Dawn costar. "This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob," she said in a candid statement. "I love him, I love him, I'm so sorry."

Both Stewart and Pattinson have stepped out publicly since the scandal broke, but neither has directly addressed the status of their relationship.
