Declan Donnelly will get married today.
The 39-year-old TV host - who is one half of presenting duo Ant and Dec along with his friend Anthony McPartlin - will tie the knot with his agent Ali Astall in his home city of Newcastle, just nine months after getting engaged.
A friend of the 'I'm a Celebrity ... Get Me Out of Here!' presenter said: "It felt right for him to go back to Newcastle because Dec is such a proud Geordie. Dec always wanted to get married before he
turned 40, which happens next month.
"The fact that he's waited so long to marry shows how serious he is about marriage vows, but he has absolutely no doubts that Ali is The One."
The ceremony will be officiated by Father Dermott Donnelly - who is Dec's older brother - with Ant taking on the duties of best man as Dec did for his pal's wedding to Lisa Armstrong in 2006.
A host of famous faces from British broadcasting are set to attend the wedding including Phillip Schofield, Holly Willoughby, Fearne Cotton, Tess Daly and Vernon Kay, Paddy McGuinness and Leigh Francis.
A source told The Sun newspaper: "It's a lovely group of people who have been close to Dec and Ali for years."
And 'Britain's Got Talent' judge Simon Cowell has also bagged himself an invite but recently admitted he wasn't sure if he'd be able to make it to the event.
He said: "I don't know if I can go but I've been invited. I'm very happy for him."
