Former glamour model Katie has taken a swipe at her ex-boyfriend following revelations he cheated on his latest girlfriend, Kelly Brook, with six other women.
She wrote in The Sun newspaper: ''One thing I don't understand is why Danny is always referred to a rugby hunk ... He can no longer hit any of the right spots on the rugby field and he certainly can't find them on a woman.''
Katie - who dated the sportsman in 2011 and is now married to Kieran Hayler - also said Danny has been in contact with her behind Kelly's back.
She continued: ''He likes to stay in touch that's for sure - even when he moves onto his next victim. My husband Kieran can vouch for that. I've poured my heart out about all this in my upcoming autobiography, so i'll spare Danny's blushes until then.''
The models have have previously clashed over Danny, but Katie appeared to offer an end to any feud to Kelly, telling her to ''stay strong''.
She continued: ''Take a leaf out of my book and follow the old adage that revenge is a dish best served cold.
''If you choose, your time will come to humiliate him in the same way he has humiliated you, me and many others. Try to be strong and stick to what you know is right.''
Kelly threw Danny out of her house on Sunday (11.08.13) and although he is said to be desperate to win her back, she has since maintained a dignified silence.
This Doctor won't be saying 'goodbye' in the same way as those who have left the series in recent years.
