Clara Berry and KJ Apa have welcomed their first child together.
The 27-year-old model gave birth to a baby boy named Sasha Vai Keneti Apa on September 23, and she's described her son as "perfection" on her Instagram account.
Alongside a photo of her newborn son's hand, she wrote: "Sasha Vai Keneti Apa, born on the 23rd of September. He is a perfect perfection. I am the luckiest to have now two men of my life, filling my heart with this cosmic gigantic vast love. (sic)"
KJ, 24 - who plays Archie Andrews in the drama series 'Riverdale' - and Clara announced their pregnancy news in May, when the model showed off her growing baby bump on social media.
The actor wrote on Instagram at the time: "she's pregnant btw (sic)"
And in response, Clara said: "We are [heart emoji] (sic)"
KJ's 'Riverdale' co-stars were quick to offer their congratulations via the photo-sharing platform.
Camila Mendes wrote: "another nenem on the way [halo emoji] (sic)"
And Lili Reinhart simply replied with a series of heart emojis.
Meanwhile, KJ previously likened working on 'Riverdale' to being in "jail".
The actor explained that he enjoyed much more freedom working on the sci-fi thriller film 'Songbird'.
He said: "I felt so free coming from a show where I feel like I’m in jail a lot of the time. There are so many restrictions on what I can and can’t do."
KJ also explained how his 'Songbird' character differed from playing Archie.
He said: "With this character, it was like, 'Wow, this is what it’s like to really express myself in a natural way.' I wasn’t covered in make-up or hair products. I had long hair and a beard. I just felt free."
