Linda, 57, joined sister Coleen on the ITV show to remember Bernie's life and her tragic battle with cancer.
Bernie was just 52 when she passed away in July 2013, after being diagnosed with breast cancer 3 years previously.
'We miss her every minute of every day' said Linda. 'On the train today coming down from Blackpool at 10.10 I thought this is the time we lost Bernie and our lives changed forever.'
3 years ago today, miss you forever and always Bernie. Thank you for everything. ðŸ’–— Linda Nolan Fansâ™” (@TeamLindaNolan) July 4, 2016
On the show, Linda also spoke about her husband's Brain's battle with cancer and revealed her devastation at his passing in 2007.
At the time she was dealing with her own cancer diagnosis and said the news hit her hard: 'I absolutely struggled, I went into a downward spiral when Brian passed away and I was on treatment.'
'Everyone who hasn't had a life threatening illness thinks you won't get through it. But you have no choice, you do get through it,' Linda explained.
Linda was diagnosed with breast cancer in 2006 and underwent a mastectomy, as well as chemotherapy. She was given the 5 year all clear from cancer in 2012.
By talking about Bernie on the show, Linda and Coleen both wanted to raise awareness of the disease and detailed the importance of getting diagnosed early and correctly.
'You have to trust your instinct,' Linda said. 'Bernie wanted a double mastectomy and they told her to not be silly, I wanted one and they told me to not be silly. Don't be frightened to ask again, ask for a second opinion. It's your body.'
They also both talked about how strong Bernie was, with Coleen tearfully saying: 'Bernie lost the battle with cancer but she never ever lost the fight.'
Bernie, Coleen and Linda formed the 70's pop group The Nolan's with sisters Linda and Maureen.
