Remember Chris Brown's lucrative "Got Milk?" ad campaign? It launched in fall 2008. And now, as a result of allegations that he assaulted his singer sweetie, Rihanna, it's over. A company rep told Usmagazine.com that Brown's "Got Milk?" promotion will cease this week. "The Milk Mustache campaign is taking the allegations against Chris Brown very seriously," a company rep tells Usmagazine.com. "We are very proud and protective of the image of the Milk Mustache campaign and the responsible message it sends to teens. Mr. Brown's ad was launched last fall and is scheduled to end this week." Guess they won't be calling up Michael Phelps anytime soon, huh? Man, it's really hard to be a spokesman these days. Who could live up to these standards?
