Curvaceous TV cook Nigella Lawson was in Tesco's Welwyn Garden City offices recently to sign copies of her latest recipe book. But could this have a wider significance?

Tesco doesn't have a celebrity chef to act as an ambassador. Instead, its adverts feature an eclectic mix of 'stars', such as bearded game show host Noel Edmonds - hardly known for his culinary skills.

Does Sir Terry fancy Nigella as his very own pet Jamie? Or does he just fancy Nigella full stop?
