Lindsay Lohan's uncle has passed away.

The 'Mean Girls' actress has been left stunned by the sudden passing of her mother Dina Lohan's brother Chris Sullivan and has rushed to be by her parent's side to support her.

She wrote on her twitter page: "My mom's brother, my uncle-whos amazing, just passed- may he rest in peace....rushing to see @DinaMLohan -i love you mommy xx

"Did Billy Joel curse us when he said, "only the GOOD die young" ??

"I don't know how to feel as I'm rushing home to my mom's house after just wrapping work nearly 3hours ago or less.... I feel sick. (Sic)"

Lindsay's father Michael - who has clashed with his ex-wife over the years - also offered his sympathy to the family.

He wrote on his twitter page: "My heart goes out to Dina and her family for the loss of her brother Chris. He was a great guy and a wonderful father. Bless them."

It was only recently that Michael had a health scare himself and admitted it meant he'd bonded with his former spouse.

Speaking about his time in hospital, which he'd been admitted to after experiencing chest pains, Michael said: "I just got off the phone with Dina and we were crying to each other."
