Family and friends of Bernie Nolan will gather at the theatre where she made her name to say goodbye to the singer and actress who died earlier this month.
The 52-year-old died after a long battle with cancer and will reportedly be buried with the ashes of her daughter, Kate, who was stillborn more than a decade ago.
Her sister Coleen told the Daily Mirror the ceremony at the Grand Theatre in their hometown of Blackpool would be "a massive celebration of her life".
She was initially given the all clear for breast cancer in 2010, but last year discovered it had spread to her brain, lungs, liver and bones.
ITV presenter Phillip Schofield, actor Martin Kemp and former footballer Gary Lineker have tweeted:
Just heard the very sad news that gorgeous, courageous and inspirational Bernie Nolan has died. Big love to @nolancoleen & all the family x
Very sad to hear of the passing of Bernie Nolan. A fabulous and fabulously talented lady. Thoughts are with the family #ripBernie
– Chris Askew, chief executive of Breakthrough Breast Cancer
Bernie was a truly inspirational woman who became a part of the Breakthrough family after her first breast cancer diagnosis in 2010. We were devastated to hear that her breast cancer had returned in 2012.
Her spirit and determination to try and fight the disease spurred us all on and will continue to do so. Our thoughts are with Bernie's husband, daughter, family and friends at this time.
– Baroness Morgan, Chief executive of Breast Cancer Campaign
This is a reminder of the devastating effect breast cancer can have and the need for more to be done to beat this disease.
Speaking after beginning her treatment for breast cancer in 2010, Bernie Nolan told ITV News that the illness had changed the way she looked at life.
"At lot of things are so less important in life now than they used to be," she said.
"You worry about how you look, what you think - I don't really care any more.
"I'm just who I am. That's why tonight I've come out without a wig to say to all those people out there who have the same illness as me: You do what you want.
"If you want to go bald, go for it. Sod what people think. You are who you are."
Singer Bernie Nolan was first diagnosed with breast cancer in April 2010.
She received the all-clear in 2012 after a mastectomy and extensive chemotherapy.
But later that year her cancer returned, having spread to her bones, brain, liver and lungs.
