As her fondness for cosmetic surgery shows, Anne Robinson always likes to look her best for the camera.

So her horror can only be imagined when she popped out to the newsagent's in an old grey tracksuit, without make-up, only to find a photographer waiting for her as she came out of the shop.

You don't get to be a multi-millionaire quiz show presenter, however, without learning how to think on your feet.

Oops - Anne Robinson spots the snapper outside the shop and emerges several minutes later in cap and coat brought down by her assistant

Miss Robinson dived back inside and called her personal assistant on her mobile phone. Moments later, the assistant arrived carrying a coat, baseball cap and oversized sunglasses.

And duly covered up, the 63-year-old Weakest Link inquisitor emerged to walk back to her West London home with a smirk of triumph.

Perhaps Miss Robinson is becoming more wary of photographers following her experience of a week ago, when pictures were published which appeared to show that she had just had further work on her looks following her facelift of 2004.

Anne with her trout pout last week, but a friend insisted that she had 'overdone the sunblock'

A leading cosmetic surgeon said he believed that fillers had been injected into her upper lip to make it fuller and to make her look more youthful.

In response to questioning about the look, a friend insisted that she had merely "overdone the sun block" - even though it was a dull and rainy day.

And Miss Robinson herself invited the Mail to photograph her at Pinewood Studios in Buckinghamshire where she was filming The Weakest Link.

Then her lips certainly appeared to be less plump. Yet on closer inspection, it appeared that the make-up artists on set had been hard at work.

The plumpness of both top and bottom lips appeared to have been reduced using skin-tone make-up to make the darker area of the lip appear smaller.
