Celebration, Celebration, Celebration! Kirstie Allsopp welcomes new baby boy

The new baby, born yesterday by caesarean section at St John's & St Elizabeth's Hospital in St John's Wood, joins Kirstie's first child, two-year-old Bay.

But unlike Bay, who was named almost at once, the new baby is so far without a name.

Kirstie admits that she and her partner, property developer Ben Andersen, who has two sons from a previous marriage, are struggling to come up with the right name.

'Between us we've got Orion, Hal and Bay so a name like John is probably out of the question,' the 36-year-old said.

'We've toyed with all sorts of names, but we have probably sought too many opinions, my mum, my dad and the boys who would probably like it to be something out of Dr Who.'

With the nursery in the couple's Notting Hill apartment due to be ready by Christmas, Kirstie, daughter of former Christie's chairman Lord Hindlipp, plans to spend the next six months at home.

She will return to work in February to shoot a new series of Location, Location, Location.
