Kieran Culkin makes heartbreaking admission as he speaks out on death of his sibling

Fans of Kieran Culkin have been praising the star after he opened up about grief, more than a decade after losing a sibling.

The Succession star has talked candidly about still being in mourning for his beloved sister, Dakota 'Cody' Culkin.

Cody died back in 2008 at the age of 30, when she was tragically hit by a car in L.A.

⁠Visiting places where you spent time with a loved one before they passed can dredge up many memories, as has been the case for Kieran.

He went to visit his family's former apartment building in Manhattan, and was overwhelmed with emotions and memories of the times they had together as a family unit.

He told CBS Sunday Morning: "We lived in a tight space where it was just seven of us running around. It was like a sort of little wolf-pack mentality."

Kieran added: “Whenever the door would open to let the kids in, I used to stand aside and make sure, and I used to count to make sure all six of them got in before I got in.

“That's how I remember growing up, too. I couldn't fall asleep until they all fell asleep. Like, I only existed because they did around me", the star said sadly.

Their close relationship was both a blessing and a curse, and it made losing a sibling near unbearable.

"To lose one was losing a big piece of myself. Losing one of my favourite people in the world, it doesn't get easier. But you get used to it”, he revealed.

He said the role of Roman on Succession allowed him to pay tribute to his late sister.

“After a couple seasons on Succession, I realised there was some stuff that Roman did that I was like, 'Oh, that's my sister. That was her sense of humour’", he shared.

Kieran added: “She could find exactly what the right thing to make fun of you was that would get to you but be really funny and make the room laugh. That was her."

Fans rushed to the comments to show their support for the actor, and to share their experiences too.

"The unusual and funny ones are impossible to lose - but what a mind blowing gift they were", one wrote.

"Awwh...bless him and his other siblings...it's not easy losing a very close sister like that...just hope they can all reminisce on all of they good times they all had with her", added another.

"Unfortunately I know your pain. Lost 2 of my beautiful sisters and to this day it doesn't get easier. Sorry for your loss, may your sister RIP", shared one fan.

"I get it. I have (had) five sisters, the youngest passed. Like you said you really don’t get over it you just get use to it. May your sister continue to rest in peace", another wrote.
