Rumer Willis and Pete Wentz are two really cool celebrities, and if they wear clothes from Wal-Mart, then I want to too! They are supporting Walmart's retail line of surf and beach wear, called Op, and of course they are just doing it because because , as we all know , only the trendiest Hollywood celebrities wear swimsuits from Wal-Mart. They aren't doing it because it is the only job they can get. Really.
