Los Angeles: Singer Adele might be one of the richest women in pop music but her credit card was still declined at an H&M's store. She was attempting to pay for some affordable fashion items at the Swedish fashion retail giant's store but had to cancel the transaction when the payment could not be authorised by her bank, reports mirror.co.uk. Describing the incident as "pretty embarrassing", Adele insisted she was able to make some purchases in a nearby store Sephora, ahead of her gig at San Jose's SAP arena. She said: "I went to H&M and my card got declined. Oh my days, pretty embarrassing. Nobody knew it was me, but I was mortified." To add to her woes, her dog Louie then got into a scrap during the shopping trip.
