As more details emerge about the alleged assault involving [artist id="1961441"]Chris Brown[/artist] and
[artist id="1940303"]Rihanna[/artist], the two singers are cancelling scheduled appearances and companies are ending endorsement deals with Brown.
Spokespeople for the artists have made no public statements in the wake of the scandal, but the news has already resulted in Doublemint Gum suspending Brown's endorsement deal, and Brown's campaign with the company behind "Got Milk?" will be ending as scheduled this week, Reuters reported.
"The Milk Mustache campaign is taking the allegations against Chris Brown very seriously," the Washington, D.C.-based trade group said in a statement. "We are very proud and protective of the image of the Milk Mustache campaign and the responsible message it sends to teens."
According to E!, Brown, who has reportedly retreated to a Los Angeles hotel, has also pulled out of his scheduled appearance at this weekend's NBA All-Star Game in Phoenix.
Brown had been tapped to introduce the players with Shaquille O'Neal before tip-off at Phoenix's U.S. Airways Center. Jordin Sparks will be singing the national anthem.
"Chris Brown has withdrawn from NBA All-Star events," an NBA spokeswoman confirmed to E! News.
E! has also reported that Rihanna has scrapped a concert scheduled for Friday in Kuala Lumpur, Malaysia.
"In light of recent events involving Rihanna, [William Morris Agency] will confirm within two weeks from now on a replacement date to be mutually agreed" upon by the organizer and the singer's camp, Pineapple managing director Razman Razali told E! in a statement.
"We sincerely regret this unavoidable shift in schedule and apologize to the fans for any inconvenience caused."
