It was a "Diamonds and Pearls" kind of night for on-again lovebirds Robert Pattinson and Kristen Stewart. No, they weren't shopping for engagement rings or anything 'Twi'-hards might start screaming over. They were on a date — at a Prince show.

The concert was an intimate affair. For the second time this week, the pint-sized performer held a "secret show" at The Sayers Club in Hollywood. RPattz, 26, and 22-year-old KStew — back together after going their separate ways last week to promote "The Twilight Saga: Breaking Dawn - Part 2" — were among the first to arrive at the venue Thursday night and the last to leave in the wee hours of the morning, reports People magazine. While they were at the club, they sipped beers and chatted with friends. Throughout Prince's performance they were attached at the hip — literally. "He was behind her — holding her around her hips," a source told People. "They were sweetly affectionate and tender."

When they headed home after the show — perhaps to Stewart's new $2.195 million mansion in the L.A. enclave of Los Feliz — they weren't as affectionate and tender with the waiting paparazzi. They ducked down in the car as they drove off. But nice try, you crazy kids — we still saw ya.

And we'll be seeing a lot more of them. With the initial international press for the movie behind them (she went to Japan; he seemed terribly unhappy in Australia), they will be promoting the film together in Los Angeles beginning on Sunday. The couple will be among the attendees at the press junket, along with the rest of the cast, including Taylor Lautner, Peter Facinelli, Elizabeth Reaser, Nikki Reed, Ashley Greene, Kellan Lutz, Jackson Rathbone, and Michael Sheen. Then on November 12, they will walk the red carpet at the world premiere of the film, which will take place in Hollywood.

Yahoo! Movies is live-streaming the star-studded world premiere, so if there is any red-carpet PDA, you can watch it all go down. Not that their rekindled relationship is completely back to normal. People magazine also reports that since Pattinson took Stewart back after she cheated on him with married director Rupert Sanders, their relationship is a work in progress. "There's still healing to do and trust issues," a friend of the couple tells the mag.

They're taking things one cuddle session at a time.
