Billi Mucklow has revealed she's expecting a baby girl with her husband Andy Carroll.

The former TOWIE star took to her Instagram account on Sunday to reveal the happy news that she's set to welcome her first daughter.

The WAG - who is a mother to sons Arlo, four, and Wolf, two - said she was 'still in shock' at the news she is having a 'pink one'.

Billi's big announcement came alongside pictures of the sweet confetti gender reveal she had with her husband and children.

Thanking photographer Sophie Dunne for the beautiful shots, Billi said she would cherish the moment forevert.

She wrote: 'It’s a GIRL! I’m still in shock I can’t believe were having a pink one'

'I will cherish these photos forever thank you @sophiedunnephotography. #BabyGirl #PinkOne #LockDownGenderReveal #TheCarrollKids'. 

Also present in the images are Andy's older children from a previous relationship, Emilie Rose, eight, and Lucas, six. 

Earlier this weekend, Billi shared a sweet snap showing her blossoming baby bump, a week after she revealed her baby news. 

She donned a skin-tight nude dress while her boys lovingly placed their hands on her stomach. 

The former reality star added a caption on the shot reading: 'Keeping My Boys And Bumpy Safe. #StayHomeSaveLifes #GoodFriday #EasterWeekend'. 

Last week, in her announcement, Billi held up an ultrasound snap alongside the children.

The former TOWIE star, who has been engaged to the sportsman, both 31, since November 2014, captioned the black-and-white image: 'Here We Go Again! @andytcarroll - #TeamCarroll #5Aside #LoveMyBabies.' [sic] 

Sharing the identical image, the athlete penned: ' Children Make Your Life Important #HappyHighFive @billimucklow.' 

The pair were met with praise from Billi's former co-stars, Mummy Diaries' Billie Faiers and newly-engaged Jess Wright, as well as Andy's sports pals, retired footballer José Enrique and Blackpool midfielder Jay Spearing. 

The couple, who live with their children in their £5million mansion in Chigwell, have yet to confirm when their baby is due, or the gender. 

Billi and Andy have been together for many years, and became engaged back nearly six years ago when he got down on one knee in Rome, Italy. 

While nothing appears to have been arranged, the blonde had previously revealed that the couple were planning to wed in the summer of 2017.

Speaking to OK! magazine at the time, she said: 'I wanted to spend a few months enjoying Arlo as a baby before we started getting busy with wedding stuff. I definitely want a massive wedding, though.' 

The Essex beauty found fame on ITVBe series TOWIE, but quit in 2013 to pursue a career as a Bikram yoga instructor. 

Professional footballer Andy kicked off his career in 2006, and has since played for Liverpool, West Ham United and Preston North End.

On transforming into a different man since his early stages of stardom, the media personality recently credited Billi for helping him 'grow up'.

The hunk said in an interview to nufc.co.uk last August: 'I’ve got no doubt that I was daft when I was here, and no doubt that I was daft for a couple of years after as well. 

'But I met my missus, and we’ve got four kids living at home now, we’ve got animals, we’ve got responsibilities. There’s no more behaviour like it was, you know. I was stupid, I was young, and I was carried away with the lifestyle that I had. 

'Now it’s completely different. I’m actually a dad, I’ve grown up, and got responsibilities, so… I’ve got a purpose.'

Despite their baby joy, a mystery injury has cast doubt on Andy's Newcastle future with the club unable to determine what the problem is or when he will return to the pitch.

Sportsmail revealed in November 2019 that the talented player was suffering from a problem around his ribs, and that has since been labelled a 'hip' issue by boss Steve Bruce.

However, sports executive Steve now says the injury is not his hip and, despite their best efforts, they have failed to get a diagnosis.
