Olympic diver Tom Daley is working on a new documentary for BBC One to bring more attention to international surrogacy laws, the Telegraph reports. Filmmakers call the British athlete an "expert through experience."

Daley, 24, and his husband, Oscar-winning filmmaker Dustin Lance Black, 44, recently became parents through surrogacy: Robert Ray Black-Daley was born June 28.

"Welcome to the world our precious little Robbie Ray Black-Daley," Daley wrote on social media. "The amount of love and joy you have brought into our life is immeasurable, our precious little son."

"Thank you for bringing so much love and light with you," Black wrote. "And thank you to those who helped make our dream of having a family into this wonderful reality."

In the hourlong BBC One film, expected to air in 2019, Daley will travel to the U.S., where commercial surrogacy is legal. It is still illegal in the U.K. to advertise for or pay surrogates anything more than "reasonable expenses."

Daley will also visit countries where surrogacy is completely illegal and meet with people who want to ban the practice entirely.

"Surrogacy is one of the most complex issues in modern society and the laws which govern it are radically different across the world," says Tom McDonald, BBC's head of natural history and specialist factual commissioning, in a statement.

"As new fathers through surrogacy, Tom and Lance are both committed to exploring all of the nuances around this very emotive subject. I'm thrilled that Tom is going to be our guide in this deeply personal and intelligent film."

Black and Daley revealed on Valentine's Day that they were expecting a child via surrogate and were met with significant online criticism.

"We have an egg donor and a surrogate and we feel very lucky," Daley responded. "I get tons [of abuse] every day, but at the end of the day, I'm married with a kid on the way and I don't care what anyone says."

Discussing the possibility of raising children in a 2015 interview, Daley said he would be the "bad cop" parent: “If the kid were to smile at Lance, he’d break.”

Daley and Black were married last May after announcing their engagement in October 2015. Daley went public with their relationship in 2013 following a YouTube video in which he spoke publicly about his sexuality for the first time.
