Natalia Vodianova is pregnant

Natalia Vodianova is pregnant.

The Russian model – who has children Lucas, 11, Neva, seven and Viktor, six, with her ex-husband Justin Portman – has revealed that she and her boyfriend Antoine Arnault will be welcoming their first child together in May 2014.

Antoine – the son of LVMH chairman Bernard Arnault and CEO of luxury brand Berluti – posted on Facebook:  »Hi everyone, big news today! Giving a little brother or sister to Natalia’s three wonderful children is something we wanted so much: and now it’s happening!

 »We’re going to have our first baby next year!!! Number four for her but number one for me… I’m a little stressed! She was tired the first three months but is fine now. (sic) »

Arnault is hoping their child will inherit the supermodel’s looks and share his sense of humour.

He joked:  »I hope he or she gets mummy’s looks (and beautiful hear) and daddy’s sense of humour!!! Pleaaaaase not the other way around! (sic) »

Natalia revealed she has been  »eating all the time » during her pregnancy and is hoping this news will help her friends understand why she has cancelled some recent plans.

She wrote:  »Please read cute post by future daddy and share our big news.

 »This will explain to many of my friends and colleagues why I have been cancelling on them so often recently.

 »One guy (it had to be a guy) who drives me sometimes said back in September to my assistant that I am having a nervous breakdown because I am eating all the time in the car! (sic) »
