On Friday, the Twilight star emerged from seclusion at Reese Witherspoon's house in Ojai, Calif., for a night out with his mates from the U.K. at the nearby Deer Lodge, a country-western bar for locals.

The group checked out the band The Jenks, and returned again Saturday.

"Pattinson came in with a few friends, like three guys. There was a big party here already and they came in to hang out with the party," a source tells WHO of the group's second outing. "There were two girls that were hanging around him, but not Rob necessarily. He seemed happy, fine."

Warmed by a couple of drinks, "He was laughing and smiling most of the time, but he was low key," the source adds. "He didn't really get up. No dancing or anything. He was totally nice and polite."

His friends, however, partied with the other rowdy guests to the sounds of The Lonely Wild, described on its website as a band that "unabashedly confront(s) political corruption, greed, and social discord in songs colored with delicate folk, bombastic rock ‘n’ roll and cinematic western flare."

Pattinson, 26, has been described as devastated by the admission by Stewart, 22, that she cheated on him with her Snow White and the Huntsman director, Rupert Sanders. Stewart and the married Sanders have both issued public apologies.
