Couples preparing for twins have to buy two of most things - including all in one suits, swim nappies and travel cots.

However, actor John Travolta and Kelly Preston will not be burdened with a jumbo shopping list, after denying they are expecting twins.

Reports across the pond had suggested the Pulp Fiction star and his wife are expecting more than just one pitter patter of tiny feet.

However, a spokesperson denied the claims, stating: "They are not expecting twins."

Preston, 47, is the latest celebrity mum to carry on having children as she approaches middle age.

Artist Sam Taylor Wood is pregnant at 43, while Italian actress Monica Bellucci, 45, is likely to be shopping for all in one suits at the moment after giving birth last week.

It is a trend that is being noted among mere mortals too - Office for National Statistics data released earlier this week revealed there has been a 50 per cent rise in British women over 40 giving birth over the past decade.
