Dermot O'Leary has proposed to long-term girlfriend Dee Koppang after a 10-year relationship.
The engagement was announced by Caroline Flack and Olly Murs live on The Xtra Factor last night to cheers and applause from the excited studio audience.
'We want to congratulate you...on your engagement!,' Caroline shouted.
Dermot, 38, apparently popped the question to TV producer/director Dee on a romantic trip to New York earlier this month, but the couple decided to keep their news under wraps - until now.
'Thanks for all the tweets tonight. Very lucky boy,' Dermot Tweeted to his 537,041 followers after the show.
The X Factor host and Dee showed their commitment by buying a £3.5 million home together in North London this April.
But when Olly asked why he'd taken so long to get down on one knee, Dermot said he was happy to take things slow.
'Well, you don't want to rush these things,' he said.
