The Piranha 3D star, who separated from the sportsman in August (13) amid cheating allegations, is now dating British model Harvey Newton-Haydon, according to Britain's The Sun newspaper.
The pair reportedly met through mutual friends and has been spending a lot of time together over the festive season.
A source says, "Kelly really likes him but has been trying to keep it quiet as she wants to get serious. She has been playing the field since Danny did what he did. Danny now realises she is well capable of moving on and it's killing him."
