Robert Pattinson and Kristen Stewart seem to be putting her cheating scandal behind them — the “Twilight” stars were “very affectionate” at a Prince concert in Hollywood this week.

Pattinson, 26, was heartbroken when Stewart, 22, his girlfriend of three years, was spotted kissing her “Snow White and the Huntsman” director Rupert Sanders in July, but he has recently agreed to take her back.

A source told us, “There are still trust issues, but both Rob and Kristen want to be together.

“Kristen was as devastated about it as he was and will do everything she can to make things right between them.”

The couple arrived together at the 200capacity Sayers Club in LA Thursday night and were “cozy and very affectionate the entire evening,” said a spy, adding: “Both loved music and were on their feet for the entire show. He was standing behind her with his arms round her. They seemed perfectly content.”

Another source told us, “Prince made everyone turn in their phones and cameras so nobody took pictures of Rob and Kristen. The couple left after his set, with Kristen clutching Robert’s hand as they were escorted out back.”

Also there were new couple Chris Evans and Minka Kelly, who witnesses said were “equally affectionate.” They started to leave about 2 a.m., only to come back in when they heard Prince took the stage again after his encore. And on their final way out, “They got to say hello and hug Prince,” we’re told.

Others who stepped out for Prince’s secret show included Joseph Gordon-Levitt, Maksim Chmerkovskiy, J
eremy Piven, Sophia Bush, Jenny McCarthy, music blogger Dr. Funkenberry and Mark Foster.

Pattinson’s and Stewart’s reconciliation will be a relief to “Twilight” movie bosses. This week the two have been busy doing separate appearances for “Breaking Dawn — Part 2.” But their much-anticipated red-carpet reunion will take place at the film’s Nov. 12 premiere.
