Big Brother 4 latecomer Lisa Jeynes has dumped royal love rat James Hewitt after watching him seduce another woman on E4's Fool Around With.

Recently, Penarth blonde Lisa, 36, told the press she was "his new Princess Of Wales" after hooking up with the ex-Army major last year.

But today Lisa told the Daily Star: "We're finished. Hewitt is a real-life love rat. He's just a reality show bore."
