He's got her, babe.
Although he is perhaps most well-known as the eldest child of Cher and the late Sonny Bono, Chaz Bono has another very important woman in his life: Jennifer Elia, his girlfriend of four years.
In part two of an interview with ET's Mary Hart, airing tonight, Bono (formerly known as Chastity) says that Elia has "been amazing" throughout the process of his sex changed, announced in June.
"I feel really grateful to be going through this with a partner," says Bono, 40.
Chaz's decision to become a man -- he says the process took "almost a decade" -- was no surprise to Elia.
"I didn't just spring this on Jennifer recently," Bono explains."This was something she knew about shortly after we met." (The pair were set up through mutual friends at a barbecue thrown at Bono's house, he says.)
Bono also fields Hart's question about the intricacies of a relationship between a woman and someone undergoing a female-to-male sex change: "Our relationship always modeled a heterosexual relationship, emotionally and intellectually," he says. "So now it does physically as well."
Cher's reaction to her child's transformation, however, remains private.
"The people in my life are just happy that I'm doing this," Bono says, "and seeing the positive effect that it's having on me."
