KJ Apa and Clara Berry are expecting their first child together.
The 23-year-old actor shared a picture of the couple sitting on a sofa, and the French model had her baby bump on display.
Clara also shared some photos of her bump on her own Instagram, and the 'Riverdale' star commented: "she's pregnant btw (sic)"
And she replied: "We are [heart emoji]"
Several of KJ's 'Riverdale' co-stars were quick to congratulate the actor.
Camila Mendes wrote: "another neném on the way (sic)"
Lili Reinhart posted three heart emojis, and Vanessa Morgan is looking forward to KJ and Clara's little one being best friends with her four-month-old son.
She wrote: "Rivers soon to be bestie"
KJ's news comes just a month after he admitted he would be willing to "drop acting" if he had a "beautiful family".
He said: "I've never been so sure of anything in my life, other than the fact that I want to be a father.
"It's a lonely place, this industry. Human interactions are no longer the same for me. I'm searching. I'm searching for genuine relationships with people who genuinely care about me and who I care about, not because of who I am or who they are.
"I don't want to be lonely for the rest of my life.
"I'm looking around me at people doing what I'm doing, putting everything into their careers and into fame and into themselves.
"I'm guilty of the same thing but I look around and I'm like, 'Wait, what's the point of all this if you can't share it with anyone other than yourself and your friends?' It becomes meaningless. I'd be willing to drop acting and all of this if I had a beautiful family. If I had to do it, I would do it."
