Usher reportedly dumped Naomi Campbell because he was "bored" with the model.
Despite claims by the catwalk beauty that she ditched the laid back singer because his entourage was too controlling, his friends have hit back saying the three-month relationship had simply run its course.
The pair's romance came to a head at last year's Billboard Music Awards when Usher, who picked up 11 prizes at the ceremony, asked his model girlfriend to accompany him.
But Naomi reportedly refused because she thought he was getting more publicity out of their relationship than she was.
However, shortly after the split, a source close to Naomi said: "Usher's camp are very controlling and wanted Naomi to behave a certain way and do as they say - including showing up to every red carpet event with him and posing for every picture. She was sick of it."
