Cory Monteith's grieving relatives have called for privacy in the aftermath of the star's sudden death as the actor's father is "too devastated" to talk about the tragedy.

The Glee star was found dead in a hotel room in Vancouver, Canada on Saturday (13Jul13) and the news sent a shockwave through Hollywood.

Tributes have poured in from famous faces and fans from across the world, and Monteith's family has now spoken out.

The star's stepmother, Yvette, who is married to Monteith's father Joe, has issued a statement on behalf of her husband, insisting the family needs time to deal with the loss in private.

She tells the Toronto Star, "We're both so... stressed out. I just can't cope with anything right now. We just need some time and privacy at this moment. (Cory's father) can't even talk to anybody right now. He's just too devastated. So am I."

Officials in the city have yet to release the star's cause of death as they await the results of toxicology tests.

Barb MCLintock, spokeswoman for the Coroners Service of British Columbia, insists results will take "several days at the earliest".

She adds, "We don't want to predict exactly how long it might take for the toxicology screen and analysis to come through. We do understand there's a lot of public interest in this case so we will try and get it done in as good a time as we can without compromising the integrity of the investigation or the testing."

Monteith previously battled drug addiction and finished his latest rehab stint in April (13).
