'He’s here!’ she announced today on Instagram. ‘Mickey Jones born today weighing 7lb 1oz and he’s absolutely gorgeous.’
Sophie revealed in a TV interview just a day before the birth that she didn’t know the sex of the baby, despite a lot of mounting pressure to have a girl after her run of boys.
'This one is... a baby, for sur,’ she said. ‘I don't know what I'm having. I've never found out.'
The star, who says she loves having a ‘very busy, eccentric, chaotic family’, often shares pictures of her kids, Sonny, 14, Kit, nine, Ray, six, and Jesse, two.
Although she says she finds a way to juggle her career with all her kids thanks to child care, the star’s new orchestral greatest hits album has now been pushed back to March.
'[Motherhood] has made me a better performer, a better artist, a happier person,’ she told Channel 4's Sunday Brunch.
'I wouldn’t say it's harder. In fact, I think it's made a lot of things have real clarity for me, actually. I wouldn’t have done half the things I’ve done if I hadn’t become a mum.'
Congratulations, Sophie!
