Superman is ready to be a super dad.

Henry Cavill, 41, celebrated Father's Day on Sunday by confirming he's preparing to welcome his first child with Natalie Viscuso, a television producer and executive.

The "Man of Steel" star shared a selfie taken in a nursery, where a crib and changing table were seen behind him.

"Happy Father's Day ye dads out there," he captioned the photo. "Turns out I shall be joining your hallowed ranks soon! Any tips??"

The actor added, "Don't worry, pillows won't be in the crib when the wee one arrives, just glue and scalpels so he or she can build Warhammer miniatures."

Cavill is slated to star in and produce a cinematic universe for Amazon based on "Warhammer 40,000," a war game set in the future that uses miniatures to depict a conflict between humanity and various threats. He is known as a longtime "Warhammer" fan and worked with Viscuso to set up the Amazon deal.

The "Enola Holmes" star, who confirmed his relationship with Viscuso in 2021, previously suggested he had a child on the way. Speaking with Access Hollywood in April, he said his parents inspired him to become a father.

"I'm very excited about it," he said. "Natalie and I are both very excited. I'm sure you'll see much more on that."

On her Instagram Story Sunday, Viscuso wished a happy Father's Day to "the soon to be father of my first child," adding, "Overflowing with love and excitement over here!"

Viscuso previously described Cavill as the "greatest man I have ever known" and wrote that she is "so, so proud of" him after he appeared on the cover of The Hollywood Reporter in 2021.

Cavill is best known for starring as Superman in the DC Extended Universe starting with 2013's "Man of Steel," as well as Geralt of Rivia in the Netflix series "The Witcher."

In 2022, the DC film "Black Adam" brought Cavill back as Superman following a five-year absence, promising he would reprise the role in future movies. "I am back as Superman," Cavill triumphantly announced after the film opened. But less than two months later, after James Gunn and Peter Safran took over as heads of DC Studios, Cavill confirmed he would "not be returning as Superman" after all.

"After being told by the studio to announce my return back in October, prior to their hire, this news isn't the easiest, but that's life," Cavill said.

Gunn subsequently cast a younger actor, 30-year-old David Corenswet, in the upcoming reboot "Superman."

But so far this year, Cavill has already headlined two new action films: "Argylle" and "The Ministry of Ungentlemanly Warfare."

In April, he told Entertainment Tonight he is "enjoying this stage of my life very much."

"I have a real sense of approaching everything with more direction now," he shared. "One of the advantages of getting older is that you have the beauty of hindsight. Now with my career especially, I've got a lot of direction ... and I'm going to focus on enjoying it more than I've been able to in the past."
