Mrs. Carter? Try Mrs. Claus.
Beyoncé shocked holiday shoppers in Tewksbury, Mass. Friday evening when she not-so-casually stopped by the local Walmart to pick up a copy of her latest album, "Beyoncé," which hit stores that day after an exclusive overnight release on iTunes a week prior.
While she was there, Bey also picked out some toys for her 23-month-old daughter, Blue Ivy, and merrily greeted fellow customers.
But an even bigger surprise came at the check-out counter, when the singer, who is married to entertainer Jay Z, took over the store intercom.
"Hello, Walmart shoppers... It's Beyoncé," she announced, "and I stopped by the store today because my record just arrived. I wanted to give everyone a little 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 erupted in cheers, and a beaming Beyoncé rang up gift cards for 750 people, according to Boston.com, totaling $37,500.
