Sorry ladies, it looks like Dec is finally off the market.
The 39-year-old I'm A Celebrity 2014 host has reportedly popped the all-important question to girlfriend Ali Astall, 36.
Ant McPartlin's lifelong friend is said to be head over heels in love and couldn't wait to ask his lady of a year and a half to marry him in Australia this past weekend.
A source told the Mirror: "His plan was always to pop the question in Oz before they started filming. They've spent a lot of time there in the past for the show and it just felt right."
They added: "Dec and Ali are completely besotted with each other. They have been best friends for a long time.
"Dec soon realised that the he’d met the girl he wanted to spend the rest of his life with and felt ready to settle down."
The insider added: No one is expecting a long engagement because Dec and Ali have known each other for so long.
"They’re keen to start a family and want to get hitched next year."
"Friends and family are delighted and see that they’re taking the next step as they’re perfect for each other."
The pair began dating last August after having worked closely together for a decade.
Groom-to-be Dec said of Ali last November: "It's going good. Everything's hunky-dory.
"It was a little strange because we've had a working relationship for so long. But because it just happened there was no big 'ta-da'. I can still fall in love easily.
"That's what is really nice because everything at home is great and work is really busy. Things couldn't be better for me at the minute."
Dec has yet to confirm the happy engagement news himself, but it seems as if a big fat congratulations are in order.
We'd better go buy a new hat!
