She's like a bootylicious little elf. Santa would be proud.  Beyoncé made it a very happy Christmas for some last minute shoppers in a Tewskbury, Massachusetts mall this week, when she popped in to plug her new album. Queen B did a little shopping herself on her Friday night visit, putting a copy of her own album and a doll for baby Blue Ivy in her cart. She then took to the store's loudspeaker, to share a nice surprise with the gathered crowd. "It's Beyoncé! And I stopped by the store today because my record has arrived," she said. "I want to give everyone a gift. For everyone in the store right now, the first $50 of your holiday gifts are on me. Merry, merry Christmas from Beyoncé!" The store handed out a total of 750 $50 gift cards in envelopes that read, "Happy Holidays from Beyoncé." Beyoncé, if you happen to be around later, you'll find us in LIDL at around 7. Sound.
