Billie Lourd's childhood with the late Carrie Fisher taught her "what not to do" as a parent

Speaking on the 'New Day' podcast, Billie said: "My main job when [Carrie] was alive was taking care of her and making sure she was OK.

"I was her main support, and I was seven, for a lot of the time, and that was really hard and that’s why I grew up really fast because I was her best friend.

"I was her mother, I was her kid, I was her everything. And that’s one of the things I’m learning not to do with my kid.

“There’s a lot of things that my mom taught me to do and then there’s a lot that is, honestly it might be more valuable, of what not to do. And that’s one of the things that I will not do to my son is put this pressure on him that I had on me.”

Carrie and her mother, actress Debbie Reynolds, died within a day of each other in December 2016 and Billie admitted she now regrets trying to keep a professional distance from them when they were alive because the 'American Horror Story' star didn't want to live in their shadow.

She said: "When they were alive, I feel like I really tried to avoid doing things in their shadow.

"We got offered all these random photoshoots … but I didn’t want to do them when they were alive, because I wanted to make sure that people knew me separately from them and now I wish I could run back and do all of those photoshoots.

"And do anything with them, really. I guess I just tried to separate myself from them more while they were alive.

"And now I feel like I'm kind of trying to do the opposite. I try to connect myself to them, because I miss them. And that's been really difficult and sad for me."
