ET was with Latin sensation Thalia at her book-signing event Thursday night in New York City, where the beauty reacted to the news that Chaz Bono, full name Chastity Bono, is in the process of transitioning from a female to a male.

Thalia tells ET that if it were her child who decided to undergo the gender reassignment process, she would be fully supportive.

"I will accept my daughter no matter what. It's my daughter and her decisions are her decisions…," Thalia tells ET.

Thalia also tells ET all about her new book Thalia Radiante: Your Guide to a Fit and Fabulous Pregnancy, on sale now. From exercise to recipes, Thalia shares her tips on staying in shape during and after giving birth!

"It's a beautiful opportunity to re-invent ourselves, to enjoy our curves, to love ourselves and to embrace it…," the star says about the book she wrote while she was pregnant.
