Announcing the news on Instagram, the couple shared a black-and-white photograph showing them on a hospital bed as Fury cradles the newborn in his arms and Hague hugs her partner.

The post was captioned "23/01/23" with a white heart emoji.

On her Instagram story, the 23-year-old posted a picture of her hugging her baby girl and wrote: "One week old today. I can't believe we get to keep you forever.

"Becoming your mum has been the best thing to ever happen to me... it doesn't seem possible but my love for you grows with each passing moment.

"There is no feeling like holding you in my arms little one, my heart literally explodes.

"Thank you for entering this world safely for us and blessing us with the gift of being your parents. We promise to love and care for you conditionally forever."

Fury, 23, shared an Instagram story of him holding the baby captioned "I'll protect you forever my little girl".

The pair, who met on the fifth series of ITV show Love Island, did not reveal the name of the baby.

The child's birth was seemingly inadvertently revealed by the forthcoming opponent of Fury, a professional boxer who is due to fight YouTube star Jake Paul on 26 February.

Announcing the long-awaited fight on Instagram four days ago, while taunting Fury, the younger half-brother of world heavyweight champion Tyson Fury, Paul said: "Tommy has no excuses now…Baby's born. Money's massive. Immigration no issue.

"Tyson promises he and Papa will make Tommy retire from boxing and change his last name if he can't beat the YouTuber."

But Love Island contestants were among those to offer their congratulations after the baby's arrival was confirmed, with Maura Higgins writing: "So so so proud of you always, she is so perfect".

Hague kept her 6.9 million Instagram followers up to date throughout her pregnancy after announcing she was expecting last September.

The video then cut to the pair holding Hague's baby bump and embracing each other.
