Sean 'Diddy' Combs has received support from an unlikely ally in his fight to escape lengthy prison time as one of his alleged victims urged a judge to free him.

The disgraced music mogul, who was recently acquitted of serious sex trafficking and racketeering charges, still faces up to 10 years behind bars after he was convicted of two counts of transportation to engage in prostitution.

But his ex-girlfriend Gina Huynh, who was identified as 'Victim Number 3' and was initially expected to testify against him before going MIA at his trial, has penned a letter to the court supporting Diddy's bid for bail.

'I do not view Mr Combs as a danger to me or the community,' she wrote in the letter, seen by the Daily Mail.

'To my knowledge, he has not been violent for many years and he has been committed to being a father first.'
