Kim Cattrall has lashed out at her Sex And The City co-star, Sarah Jessica Parker, saying: "You are not my family. You are not my friend."
She's taken exception to what she calls Parker's "continuous reaching out" following the death of Cattrall's brother.
Her brother Chris (55), was found dead last Sunday after going missing from his home in Canada.
In September Cattrall ruled out appearing in Sex and the City 3, saying her relationship with her co-stars was "toxic".
Writing on Instagram, Cattrall told Parker to "stop exploiting" her tragedy.
