Report: Robert Pattinson and Kristen Stewart kiss and make up, will appear on 'Twilight' red carpet

'Twilight' star Robert Pattinson and co-star Kristen Stewart are an item again, just months after he walked out on her, The Sun reports.

Pattinson, 26, was revealed to have had a heart-to-heart with the tearful Hollywood beauty, 22, over the weekend and forgiven her "stupid mistake."

A source told The Sun how Pattinson had set up home with the brunette once more, adding: "They pretty much decided they couldn’t live without each other."

"Kristen poured her heart out to Robert and told him it was a one-off and a mistake," the source told The Sun.

Pattinson quit their Hollywood home in June over snaps of Kristen cheating on him with another man — married film director Rupert Sanders, 41.
