The London socialite – who tied the knot with Professor Green in a romantic ceremony in Somerset last year – recently revealed she still feels pretty young to have children but is aiming to have a baby before turning 30.

‘It’d be so hectic having kids around at Christmas,’ she told Hello! Magazine. ‘I’d be too exhausted to host if I was pregnant or had a young baby. I’d be like, "Let’s all just check into Claridges."

'But Stephen will be such a hot dad. There’s nothing sexier than seeing a man with a baby.'

Millie and her husband, real name Stephen Manderson, have just moved into their renovated home and are looking forward to spending Christmas together in it.

The former Made In Chelsea star said the so-called nursery room is a crash pad for friends who drink too much at one of their dinner parties.

She added: ‘Having this new house is such a big deal for us. This is our baby, really.'
