TALK about paying it forward with a twist.
When New Jersey grandmother Ruth Reed made a vow to help someone out with their bills once a week, she ended up footing the bill for a country music star worth an estimated $75 million.
Ms Reed, a retired schoolteacher, was gobsmacked when she realised the shaggy-haired man she was helping out with a few dollars to pay for his food and coffee at a service stations as Aussie country music star Keith Urban.
She says met Urban at a Medford Wawa ahead of his concert Friday night in Camden, New Jersey.
She has made a resolution to help Wawa customers and jumped at the chance when the man ahead of her was short a few dollars.
"For three years, I have made a resolution to once a week treat someone at Wawa," Ms Reed wrote in a Facebook post.
"Occasionally it happens more than once a week. This man was short a few dollars. He asked a lady with him if she had money. I jumped in and said I would pay and explained why. He thanked me and asked my name."
"I asked him his and he told me it was Keith. I said that he did look like Keith Urban. He said he was."
A sceptical Reed didn't quite believe him, asked where his wife, Nicole Kidman was, and then asked his bodyguard to confirm she was talking to the musician.
She said: "It was then I realised what an idiot I was."
The grateful country music star then offered to take a picture with the delighted do-gooder in the car park.
Ms Reed promptly posted the celebrity encounter to her Facebook page, describing it as "another Ruth Reed moment".
