Ruth Reed, from New Jersey, USA, thought she was helping a down-and-out man pay for his food at a petrol station.
Ruth Reed and her husband have made it a habit to pay it forward to customers at a Wawa convenience store in New Jersey.
The country music star thanked Reed and introduced himself as Keith - and she told him he looked like Keith Urban. When she remarked that he looked like Keith Urban, he said that he actually was the famed country music performer.
Urban, who was in town for a concert at BB&T Pavilion in Camden on Friday, told Reed she could ask his bodyguard for confirmation.
"It was then I realized what an idiot I was".
So on August 3rd, when the customer in front of her at the store was having an issue at the register, she jumped at the opportunity to help.

The odd behavior led officials to believe the man was under the influence of alcohol or drugs, Oroville Lt. He was reportedly walking around shining a flashlight into his own face.
"And I just fell apart, fell apart and he was gracious", Reed said.
"For three years, I have made a resolution to once a week treat someone at Wawa", Reed wrote in a Facebook post that was put on Twitter by one of her former students. "And who was that woman you were with?" "I said, 'OK, I don't think she would lie to some old lady'".
Keith Urban was buying some things at an New Jersey convenience store when a local teacher offered to pay for him without even knowing who he was.
"And he really could have said 'Lady get away from me, ' and he didn't, he was very kind".
"And I just fell apart, fell apart", she said. Still, she managed to snap a photo with Urban.
