Despite being far from a conventional family, Thomas Beatie and his new girlfriend are keen to have more children but they don't yet know which one of them would carry the next baby.

"Hypothetically we have talked about starting a family together," the famous 'Pregnant Man' told Anderson Cooper in an upcoming episode of his talk show.

As Breaking Celebrity News previously reported, Thomas, 38, first made headlines four years ago when he gave birth to a baby girl with then-wife Nancy Beatie who was unable to conceive, but after three children their marriage fell apart and Thomas began dating their children's daycare director, Amber Nichols.

"You've had bottom surgery so you could have a baby again but it would be by C-section obviously," Anderson said in the interview with the new couple.

"Yes, the surgeon highly advises against it, yeah, I might bust a stitch or something," explained Thomas, who after being transgender for 15 years just had a full sex-change operation in February but kept his womb.

Amber, 42, agreed that she definitely wants a child of her own, though, "Not today, in the future."

However, the couple is realistic that it might not be as easy as it was in the past for Beatie, who is prepared for the complicated process.

"We would have to check out our fertility options. Right now we have some of the same sperm used with the three children that I've had," he explained. "We have two vials left at California Bank and there's a clinic in San Francisco that we might seek advice from."
