Mandy Moore has described her family as ''extraordinarily close'' with no secrets.

The 'This Is Us' actress' mother Stacy left her father Donald for a woman a decade ago and both of her brothers are openly gay and she is proud that her loved ones are open about who they are.

Mandy, 33, told the new issue of PEOPLE magazine: ''Nobody is hiding who they are. There are no secrets in our lives. I love and support my mom and my brothers with my whole heart. And nothing makes me happier than seeing anybody live their authentic self, and to choose love. If anyone can find love, I support it, I salute you and I celebrate that.''

Mandy is naturally ''protective'' of her mother and siblings but she's optimistic that society is getting to a point where people's sexual orientation is not such a big deal.

She said: ''I feel a certain amount of protectiveness. I definitely won't stand for that. But I feel like we're at a time in our culture when we're able to have a much more open dialogue.

''I'm encouraged and excited that eventually we're going to get to a point where none of this matters. Sexual preference or orientation just won't factor in anymore. I think we're inching closer to that.''

Meanwhile Mandy - who is engaged to her boyfriend of two years, Taylor Goldsmith and was previously married to musician Ryan Adams - recently revealed that she sees motherhood as the ''next chapter'' in her life.

Speaking in a preview clip for Sunday TODAY With Willie Geist, she said: ''I've always wanted to be a mom. I think that's definitely the next chapter for me ... I've been waiting for the right person and the right time.''
