Since then, social media has been aflood with condolences and support for Lourd, who is Fisher's only child.
Lourd followed her mother and grandmother into show business.
In her essay, Joely also recalls growing up with her half-sister, who was an idol and always made her feel "more interesting by osmosis" and admits Carrie would have appreciated her dramatic exit, adding: "She just might have wished for another couple of decades before making one".

Support for Lourd has no doubt come from a number of places but a particularly vocal source has been her Scream Queen co-stars.
We can't even imagine what she must be going through. "She started it. It's her fault".

With the two caught kissing in the photo, Palmer captioned her post, "Omg omg omg OMG", as reported by E!

"This girl is one of the strongest, most fearless individuals I've ever met". Absolutely attractive inside and out.
All our love to Billie Lourd at this incredibly hard time.
