Bogota, Colombia ? Naomi Campbell has spoken out in support of Kate Moss, who has lost three modeling contracts and is being investigated by London police on allegations that she used cocaine.

“Kate Moss is my friend … I think it’s like everybody is being bad to her,” the supermodel told a news conference Sunday in the Colombian capital where she was judging a modeling competition.

“It’s not the first time it has happened in the world … it’s really like a vendetta,” said Campbell, who has said that she nearly self-destructed from her use of cocaine.

Pictures in a British tabloid appeared to show Moss using cocaine. Moss, 31, issued a statement last week apologizing to “all the people I have let down.”

“I take full responsibility for my actions,” she said. Her statement stopped short of specifying whether she had used cocaine.
