How reliable are British tabloids? Not very. But for the sake of our sanity, let's assume that The Sun is correct, and Robsten are back together.

"They pretty much decided they couldn't live without each other," said a source The Sun probably made up. (Actually that might have been borrowed from one of the Twilight books. Stephenie Meyer is a source, right?)

According to the report, Kristen and Rob had a heart-to-heart, during which she assured him that her fling with Rupert Sanders was a one-time mistake. (I thought it had been going on for months?) Rob has forgiven Kristen's "stupid mistake," and "after a lot of long tearful talks," they've decided to give it a go again.

This is going to be a difficult rumor to confirm, as both actors are notoriously secretive about their personal lives. But they will be back on the red carpet together for the premiere of The Twilight Saga: Breaking Dawn — Part 2, at which point we can analyze the hell out of their body language and draw our own unsubstantiated conclusions.
