Jonny Fairplay’s model wife Michelle Deighton has walked out on the Survivor bad boy, taking their young daughter with her and alleging he’s an unfit dad, RadarOnline.com can exclusively reveal.

The former America’s Next Top Model contestant called time on their three-year marriage and took their 3-year-old daughter Piper, from their home in Virginia on June 8, 2011.

A source close to Deighton has hit back at accusations that she has been refusing Fairplay access to their child since their split, insisting that she is more than willing for the two to spend time together, but wants to monitor the visits as she worries that Fairplay is negligent.
