"I pulled into the parking lot," she said, "and sure enough there were these enormous tour buses, and I thought, 'Whoa.'"
Her sergeant met her at the hotel parking lot.
"I got out of my car and said, "Sarg, this guy says he's Bob Dylan,'" Buble said. "He opened the car door, looked in, and said, 'That's not Bob Dylan.'"
"So we go over to the tour bus and knock on the door and some guy answers and I say, 'Are you missing someone?'"
"Who's asking?'' came the reply, according to Buble.
"I was in full uniform, so I say, 'I'm asking! I'm the police.'"
Eventually, the police were shown Dylan's passport, which Buble said she looked at, saw the legend's name, and rather sheepishly handed it back to Dylan's manager.
"OK,'' she recalled saying as she smiled. "Um, have a nice day."
A police department source said Buble had taken her share of good-natured ribbing from some of the older officers.
"To really appreciate the story from our end, you have to see Kristie," one cop said. "She looks like a 16-year-old kid, next to this living legend. It was unbelievable."
In fairness to Buble, Dylan has a long history of intentionally seeking anonymity, often with hooded sweatshirts and other limited disguises.
In October, 2001, he was held up at a checkpoint at Jackson County Exposition Center in Oregon as he attempted to get into the backstage area of his own concert, according to the Associated Press.
