The English football star, who played underage for the Republic of Ireland, is celebrating with Atwood who gave birth to Mila Rose Grealish, on September 27.

The couple have now posted a snap of their new-born little girl holding his finger while wrapped up in a patterned baby grow and a knitted blanket.

Writing over the black and white photo, Jack simply captioned the post ‘Mila Rose Grealish’.

Fellow teammates including Marcus Rashford offered their best wishes, while Arsenal stars Declan Rice and Alex Zinchenko also added their congratulations.

Fans and the couple’s other celebrity friends also reacted to their Instagram post to congratulate them as they became a family of three.

Jordan Pickford’s partner Megan wrote: “Perfection, love you so much already Mila Rose. Auntie Megs can’t wait to buy you frilly socks and tutus xxx.”

Danielle Lloyd offered: “Congratulations to you both”, while Love Island stars Tasha Ghouri and Zara McDermott added: “Huge congratulations.”

Jack and Sasha have had an on/off relationship since they met school at St Peter’s Roman Catholic Secondary School when they were 16.

They announced they were having a baby in July, when they shared a picture of Jack cradling Sasha’s bump, with the new mum captioning the post: “Half of me, half of you – beyond blessed.”

Jack added: “Life’s biggest blessing.”

Jack helped Manchester City’s victory against Fulham at the Etihad over the weekend, having missed his side’s clash against Newcastle at St James Park the day after Sasha had given birth.

The attacker also sat out Manchester City’s Champion League game last week against Slovan Bratislava where the blues won 4-0.

Sasha had previously revealed how she struggled with finding clothing that fit while seven months pregnant,

Sasha had shared in one video that while she loved her bump, it had made finding the perfect outfit more difficult.

She explained how everyday outfits like “sweats and comfies” aren’t suitable for all occasions, especially when heading out to a celebratory dinner.

Meanwhile, after a difficult season for Jack in which he suffered several injuries before missing out on the England squad for Euro 2024, he was officially reinstated in August.

Last month, Declan Rice and Jack scored England’s goals in their 2-0 win against Ireland in the Nations League, after both represented the Boys In Green at international level before switching their allegiances to England.

Back in December, the Manchester City star admitted how he was left “devastated” after his £5.6million mansion was raided by thieves.

They made off with an estimated £1m in jewellery and watches while he was away at Everton on playing duty.

Sasha was at home with 10 family members when the break-in occurred.

Having quickly raised the alarm, a massive search was initiated involving helicopters and dogs.

Jack wrote on Instagram after the incident: “I can’t begin to explain how devastated I am over the burglary that took place at my home. My family means the world to me and nothing is more important than ensuring their safety.”
