Abbey Clancy and Peter Crouch announce they're expecting their fourth child

Abbey Clancy and Peter Crouch have announced they're expecting their fourth child.

The pair, who already have three children together, took to social media to announce the happy news that they will be adding to their brood.

The expectant mum, who's currently on holiday in Dubai with her family to celebrate the beginning of the New Year, shared a snap of herself wearing a bikini and cradling her blossoming baby bump.

Referring to Peter's football career, she wrote in the caption: 'When a hatrick just wont do !!!#babynumber4'.

The soon-to-be dad also shared the exciting news on Twitter, writing: 'Baby no 4 on the way ❤️❤️❤️❤️ I blame @OfficialClancy for looking like this.'

Many of the couple's fans were quick to congratulate them on the news of their fourth bundle of joy. One said: 'This is so exciting ❤️. Huge congrats to all of you.'

Another wrote: 'Congratulations to you all lovely news ❤️💗.'

A third commented with helpful advice for the Abbey and Peter: 'Huge congratulations! I’ve got 4.... 3 to 4 is much easier than 2 to 3!!'

It seems the pair might have changed their mind, as Abbey said their third child would be their last when she was pregnant in 2017.

She told OK! magazine at the time: 'I think this will be the last baby I have so I just want to embrace it.

'It was a bit of a shock and I’ve been very ill. I’m quite sick when I’m pregnant, but it’s fine.'

Speaking about how she deals with the changes her body goes through during pregnancy, Abbey added: 'I try not to get too hung up about my body changing because it’s natural and I think it’s a healthy sign if you’re growing with the baby.'

Abbey and Peter have been married since 2011, and they already share daughters Sophia, seven; Liberty, three; and 11-month-old son Johnny.

Congratulations to the family!
