A woman thought she was paying for a man’s cup of coffee at a gas station on Friday, but it turned out to be country music star Keith Urban.

Ruth Reed has pick up the tab for customers at a N.J. convenience store before, so when Urban was short a few dollars, the substitute teacher stepped in to help, the man who didn’t have enough cash on him.

My favorite story of the day is how my 3rd grade teacher thought @KeithUrban was down on his luck and couldn’t pay for his wawa snacks so she bought them for him. What an angel. pic.twitter.com/mJccVOQWtp

Keith thanked Ruth and said his name was Keith, prompting Reed to comment on his resemblance to Keith Urban.  So, Ruth asked his bodyguard to confirm that he was actually the famous musician.  “It was then I realized what an idiot I was,” Ruth said in the Facebook post.

Keith Urban is set to perform Friday evening in Camden.
