Now that Kristen Stewart and Robert Pattinson are done making up, they're back to shacking up!

"They are living together and have reconciled," an insider tells Us Weekly in the new issue, on stands Friday.

But they haven't exactly returned to the way they were before July, when Us broke the news that the Twilight actress, 22, had cheated with her Snow White and the Huntsman director, Rupert Sanders, 41.

As Us revealed last week, Pattinson, 26, and his estranged love recently "had a dramatic makeup." But a source tells Us the British hunk "is extra-sensitive right now. He's insecure."
