Kelly Brook, Harry Enfield and Carol VordermanHarry Enfield, Carol Vorderman and Kelly BrookWhat the heck is going on with Kelly Brook?

We're used to seeing this lass posing in her panties...

But it seems that she's had a secret hidden.

She's really a boffin.

Or at least she can be for the right price - Kel has stepped out as the face of the newly remade Tefal ads.

Come now, how could you forget the Tefal boffins with their overly large foreheads?

Take a look at Kel, we're sure she'll jog your memory.

Kelly Brook and Harry EnfieldHarry and KellyYep bosses have re-jigged the old 80s ads using Kelly Brook, Carol Vorderman and Harry Enfield.

But we don't know if they'll regret doing it - getting their bonces that big required Kelly and Harry to sit for five and a half flamin' hours as they had prosthetics fitted.

A spokesman for the company told PA: "These adverts were hugely popular in the late 1980s and, with the introduction of some well-known faces, we believe will be just as popular today."

Keep your eyes peeled for Kel's mahoosive head on your small screens early next year.
