Pattinson was spotted Saturday night with a few mates at Deer Lodge, a country-western bar in Ojai, reported Us magazine.
The 26-year-old British actor "seemed to be having an amazing time" one eyewitness said, adding that the "Twilight" star had "a few drinks and laughs" with a group of friends as live country music played.
"He looked like a guy that was just trying to enjoy himself and get away... seems like a good kid!" A second eyewitness explained that Pattinson "kind of blended in" with his friends - a "group of good looking guys that dressed 'hip LA'".
Largely ignoring calls and texts from a contrite Stewart, 22, Pattinson has been "a total mess," a source said. "He's questioning everything."
