Robert Pattinson and Kristen Stewart are "leaning on each other" again.

Robert was left heartbroken earlier this year when pictures of Kristen getting cosy with married filmmaker Rupert Sanders emerged. The Twilight hunk was said to be in turmoil following Kristen's betrayal, but it's now thought he has forgiven his cheating girlfriend.

"They're starting to lean on each other for support as they open up about the emotional turmoil they've both gone through," the source told British magazine Heat.

"Neither of them wanted this to be the end, and, no matter how badly Rob has been hurt, he still loves Kristen deeply.

"He's worried about what she's been going through."

Robert and Kristen are said to be moving into a secluded Los Angeles home together and are hoping to rebuild their broken relationship.

They are due to step out to promote the final Twilight film Breaking Dawn - Part 2 in November, but sources insist they are "focusing on themselves for now".
