The Ryan Gosling baby has arrived.
It came as a shock, considering many fans weren't even aware Mendes and Gosling were a romantic item once again.
And not everyone took the pregnancy announcement so well...
Neither Mendes nor Gosling has spoken publicly about their child or relationship status this summer, as the actress kept a very low profile over the past few months, making a point to cover up her bump any time she did go out in public.
But even if the baby wasn't planned, insiders have said that Gosling has embraced his role.
He's been doting on Mendes non-stop since he learned he was going to be a dad.
"Ryan goes out and gets the groceries. [Eva's] been wanting pasta, and he's cooking her meals," a source told Us Weekly in mid-July. "Ryan has already stepped into the role of caring father-to-be."
Really, would you expect anything less from Ryan Gosling?
Mendes and Gosling first started dating in fall 2011 after costarring in The Place Beyond the Pines. That same year, Gosling told UK newspaper The Times that he would "make movies until I make babies."
So while we send the couple our best wishes, we now ask our of fear: Will Ryan Gosling retire?!?
