Chris Brown and his girlfriend Rihanna have pulled out of more performances, after Chris was questioned by police.
They had been due to perform at the Grammy Awards in America on Sunday, but both decided they didn't want to.
Now Chris has been dropped from an ad campaign for chewing gum until the matter with the police is sorted out.
He's also pulled out of an appearance at a basketball match. Rihanna has put off a concert due to take place in Malaysia on Friday until a later date.
Chris was questioned by police
Chewing gum company Wrigley said in a statement: "We have made the decision to suspend the current advertising featuring Brown and any related marketing communications until the matter is resolved."
Both Chris and Rihanna had been nominated for Grammy Awards, and went to a pre-awards party together on Saturday evening.
But on Sunday, Chris was questioned by police over an argument he's said to have had with a woman.
Officers in Los Angeles said the woman, who hasn't been named, had been hurt, and had accused the singer of attacking her.
Chris was later released on bail, which means officers have let him go home while they carry out investigations.
