Pippa Middleton's Split with Alex Loudon!!

Is Pippa Middleton still seeing Alex and moving in with her boyfriend Alex Loudon or are they splitting up after a year's romance due to the fame and following Pippa has amassed after the wedding of her sister Kate? Personally, this Blog is a fan site and not a rumour mill, and from all previous posts I think Pippa seems to be warming up to her beau, so does anyone truly know?
