The Morning After Another Spears Wedding

After celebrating her brother's wedding the night before, a corporate casual-clad Britney Spears did what every fallen pop star on a comeback does ... hit the local Wal-Mart.

With a Sonic drink in hand and male pal at her side, the 27-year-old mother of two stopped by the discount chain in McComb, Mississippi.

Tomorrow would have been Brit and her first husband Jason Alexander's five-year wedding anniversary.
