Well what a coinsidence! I was at a party recently & the host was a Mrs N too, (actually a Mrs Newport - are you her?). At this party I was also told that Michael Aspel had fathered several famous children. Surely if this were true, it would have been made common knowledge years ago! Anyway, are you Mrs Newport?
There was nothing in the program to suggest it was a spoof and it is hard to imagine that all those famous kids would take part, Yet. . .
Who would have thought that Melinda Messenger, Mel B and Gail Porter could be sisters not to mention all the others (20 odd at the table).
If it is a joke it is a daft one if it does not even tell you at the end.
