US TV host Barbara Walters has announced that moustached Beatie revealed that he had not started taking testosterone again after the birth of daughter Susan so he could have another baby, reports the Sun.
She said on her daytime show The View: "I asked him if he was pregnant again, he said yes."
He told Walters the baby is due on June 12 and added: "I feel good...everything is right on track."
Beatie grew up in Hawaii as Tracy Lagondin, but began to live as a man when he was in his twenties.
He had breast surgery to remove glands and flatten his chest but kept his female reproductive organs.
He has been married to his wife, Nancy, for five years and the couple bought sperm from a donor when they decided to start a family.
Beatie gave birth to their baby daughter, Susan, the natural way, after a lengthy labour.
