In May, the musician shared the pregnancy news on Instagram by posting a personal photo of Berry exposing her pregnant belly while sitting next to him on the couch. It had no caption, but the picture said it all.

Berry also confirmed the news by posting part of her full maternity photoshoot done by the talented Hart Denton to her Instagram page, tagging Apa on her belly. She captioned her post with a chef emoji.

“She’s pregnant btw,” Apa commented on her post, to which Berry responded, “We are.”

Dating rumors of the pair started in late 2019 after they were spotted engaging with each other on social media. Eagle-eyed fans spotted them liking each other's Instagram photos. Apa made his relationship with Berry Instagram official in 2020 by posting a PDA-filled snapshot, which has since been deleted.
