Dermot O'Leary and Dee Koppang have been together for 10 years

X Factor host Dermot O'Leary is set to marry fiancée Dee Kopping next week after getting engaged last year.

The couple have been together for 10 years and are finally getting hitched in an old-fashioned traditional ceremony on Friday 14 September.

‘It's going to be the full works, in a church because Dermot's Irish Catholic,' says TV producer Dee.

But the pair are still inviting some of Derm's showbiz mates, including his pals from The X Factor. Amongst the guests will be One Direction, who came third on the hit show in 2010.

The bride-to-be might be less pleased about the fact that Dermot, 39, is so busy with the TV talent search he's had to put off the couple's honeymoon until after the series ends.

Derm recently admitted that he's not nervous about marrying long-term partner Dee though.

‘We've lived together for 7 years and been going out for 10 years so we are settled down already,' he told the Daily Mirror.

‘There's no sort of raucous bachelor days to put behind me when we get married.

‘I love my girlfriend and the woman that will be my wife and we are really relaxed with each other.'
