Many other fans have been telling Dec and Ali that they'll be great parents, while wishing Ali a happy and healthy pregnancy.
And, of course, there were the inevitable "very small man" jokes about the upcoming arrival!
Well, someone had to say it!
Dec and talent manager Ali announced their happy news on Sunday evening, after it leaked earlier in the day in a tabloid newspaper.
Alongside a beautiful picture from their wedding, Dec told fans: "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. Thanks for all the love, we really appreciate it."
The couple wed back in 2015 at a star-studded ceremony attended by the likes of Dec's telly partner Ant, and fellow presenters Holly Willoughby, Phillip Schofield, Paddy McGuinness and Fearne Cotton.
They tied the knot at St Michael's Roman Catholic Church in Dec's native Newcastle in August, after getting engaged the previous November in Australia.
Dec later told The Jonathan Ross Show that he'd proposed as the sun went down on their final day of the trip.
"It got to the last evening and we'd organised dinner on the beach and we went round to one side of the island, the only place on the island where you can see the sun set, and we just went round and we watched the sunset go down and we did it there, it was lovely."

He said: "Absolutely at some point, when the time is right... We'll have to put some time in the diary. [Laughs] Things are pretty busy!"
