Charles Melton is set to become a dad

The 35-year-old actor's artist girlfriend took to Instagram to share a series of images showcasing her blossoming baby bump, including one of the father-to-be kissing her belly.

The carousel, posted on Saturday (04.01.26), was captioned: "making a lil family. (sic)"

Charles' Warfare co-star Michael Gandolfini commented: "Mom and dad!!! Love you both so much."

The pair have kept their relationship out of the spotlight.

However, DeuxMoi received a tip that Camille was pregnant, telling the gossip outlet "fans are slowly discovering the news".

Charles' past romances include his Riverdale co-star Camila Mendes.

The 31-year-old actress previously admitted she found it "hard" to film Charles when their relationship ended.

Camila confessed to feeling awkward about playing the on-screen love interest of her ex-boyfriend.

During an appearance on the Armchair Expert podcast, she shared: "Obviously, right when [a break-up] happens, it's hard and it's emotional. It's the worst.

"But it's hard because the timing of the show. Anytime we started to hook-up off set and knew that something was brewing, our characters would start dating. But they didn't know. No one knew. The writers would just naturally make it happen."

The celebrity duo had an on/off relationship for years. However, they called it quits for the last time before the final season of Riverdale and Camila was able to enjoy her last season on the hit TV show.

The brunette beauty explained: "When we came back for the last season, there was a definite air of, zen, we're past it, and we worked together a lot as well but not in a romantic capacity. It went super smoothly last season. I think the whole last season felt different."
