Declan Donnelly described himself as "head over heels" as he announced the birth of his first child with wife Ali Astall.

The TV presenter, one half of Ant and Dec, revealed the news and the name of his new daughter on Twitter.

He posted: "Ali and I are thrilled to announce the arrival of our baby girl, Isla Elizabeth Anne."

He added: "Mother and daughter both doing well, Dad is head over heels! D x."

Donnelly, 42, also shared a picture of his baby daughter's hand wrapped around his finger.

The Britain's Got Talent host married Astall, his former manager, in 2015, and they announced they were to become first-time parents earlier this year.

They announced they were set to become first-time parents after rumours began to circulate earlier this year.

The new arrival comes days after it was confirmed that Donnelly will head to the Australian jungle to present I'm A Celebrity... Get Me Out Of Here! later this year alongside Holly Willoughby.

This Morning star Willoughby is filling in for Donnelly's long-time presenting partner Ant McPartlin, who is taking a step back from TV commitments until next year.

McPartlin admitted to drink driving after an incident in March which saw him banned from the road for 20 months and fined £86,000.

“These are big shoes, not to fill, but just to keep warm for a little bit," said Willoughby as the news of her new role was announced.

Ant and Dec have presented the reality programme together since it began in 2002.

The news of Donnelly and Astall’s new-born child was welcomed by a parade of popular figures, including This Morning host Philip Schofield who said he “couldn’t wait” to meet her.
