The 42-year-old television presenter - who is most famously known as part of presenting duo Ant and Dec alongside Ant McPartlin - and his wife Ali Astall have welcomed a baby daughter into the world on Saturday (01.09.18), whom they have chosen to name Isla Elizabeth Anne.

Posting a picture of Isla's tiny hand wrapped around Dec's finger on the official Ant and Dec Twitter account, Dec wrote: "Ali and I are thrilled to announce the arrival of our baby girl, Isla Elizabeth Anne, who was born just after 9 o'clock this morning. Mother and daughter both doing well, Dad is head over heels! D x (sic)"

And just a couple of hours later, the 'Britain's Got Talent' star's regular co-host also took to the account to express his joy at Isla's birth.

Ant - who has been taking time away from the spotlight after he was convicted of drink driving earlier this year - wrote: "Welcome to the world baby Isla Elizabeth Anne. Can't wait for cuddles. I love you already!!

"Uncle Ant xxxxx (sic)"

It wasn't just Ant who had a congratulatory message for Dec and Ali though, as their showbiz pals Amanda Holden and Phillip Schofield were also among those to share their well wishes.

Phillip tweeted: "The BEST news! Congratulations and welcome Isla. Can't wait to meet you (sic)"

Whilst Amanda added: "Just the best news ever. And another girl in the @BGT family !! It just gets better!!! (sic)"

Dec confirmed he and Ali were expecting a baby on social media earlier this year, after the news was leaked "earlier than [they] had hoped".

He wrote at the time: "Just wanted to say thank you for all the lovely messages. The news has sneaked out a little earlier than we had hoped but Ali and I are delighted to be expecting our first child. (sic)"
