The presenter was a firm favourite on Ministry of Mayhem and it certainly seems like she had a lot of fun if an unearthed throwback clip is anything to go by.
The blonde beauty can be seen dressed in a plunging green bikini and straw hula skirt as she presented a segment for the show.
The 36-year-old risked spilling out of the racy number as she leaned forward and flashed her ample cleavage.
Fortunately for the mum-of-three, she wore a floral necklace which protected her modesty as she enthusiastically encouraged viewers to call into the programme.

Holly’s piece to camera was unfortunately interrupted when her co-hosts decided to throw a bucket of water over her.
She could be seen giggling as her fellow presenters continued to drench her as she struggled to finish presenting her segment.
But it all became too much for Holly who gave up trying to host the kids show and demanded that she was helped to dry off.
She could be heard shouting: “Get me a towel.”
