In an interview with Women's healthHough opened up about her sexuality and shared details of a candid conversation she had with her then-husband Laich.

"I (said to him), 'You know I'm not straight, right?' And he said, 'Excuse me, what?' I was like, 'I'm not. But I choose to be with you'” she said then. "I think there's a safety with my husband now that I'm unpacking all of this, and there's no fear of saying things that I've been afraid to admit or felt ashamed or guilty about because of what I was told or how I was raised."

During her appearance on the "Jamie Kern Lima" podcast, Hough reflected on her journey of self-discovery regarding her sexuality. The former professional host of "Dancing with the Stars" said that at first she "didn't know what (she) was attracted to", but in the end she decided to stay committed to her then-husband Laich.

"Coming out is one of the most vulnerable and powerful things you can do. For me, it's not about being straight or gay or queer; it's more about learning what love is, and I love people," she said, per Us Weekly. "It's a freedom of love that I started to experience seeing people because I was able to shed a layer of protection instead of being so internalized."

Hough added, "So I started seeing people and seeing their hearts and seeing their beauty and their essence. I was like, 'Wow, I love people and I don't know if it's sexual attraction or this attraction, but I'm just seeing with people.' It was such a beautiful discovery.”
