Ash and Demi went to the ArcLight cinema in Hollywood to see Russell Brand's latest comedy 'Get Him to the Greek' over the weekend but Ashton was reportedly left red-faced when his credit card was declined when he tried to pay for popcorn.
A source at cinema told In Touch Weekly magazine: "The manager rushed over, apologized and gave them everything for free. Ashton didn't seem embarrassed at all. They just laughed it off."
It's strange that someone with boatloads of money would get his card declined, but at least he was a good sport about it!
