Pop superstar Britney Spears saved her millions by taking a shopping trip to a London budget store. The Toxic hitmaker, who is a big fan of discount stores, made a quick visit to a branch of cut-price shop Poundland to buy matches earlier this week (begs14Oct13). In an interview with U.K. chat show host Alan Carr, Spears says, "I went (to Poundland) today and got matches, they're actually this little, they're like the tiniest matches you've ever seen in your life." The star also insists she was able to hide her identity by wearing a disguise, adding, "Usually I have glasses on and no one recognises me, I just go in and I'm really into what I'm doing, I get into it and it's really fun." On Tuesday (15Oct13), the singer turned her back on luxury transport by taking a ride in a double-decker bus for a press conference. Spears is in London to promote her upcoming album Britney Jean and her two-year Las Vegas residency, which is due to start in December (13).
