The presenter mentioned her sister during a discussion about guardian angels on the daytime show.
Ruth, 60, revealed a moment she saw a white feather in her garden and thought it was a sign from Julia.
What did Ruth say?
Ruth, who lost her sister last year, told her co-stars: "Personally I don’t believe in ghosts and spirits.
"I believe in a higher being and spirituality things, but I don’t believe I have a guardian angel as such."
She continued: "I saw a white feather in the garden that was kind of stuck to the brickwork and I had that moment where I thought, 'Is that my sister?'"
"I just had that notion because I want it to be obviously, and then I do that, 'No it’s not your sister, it’s just a birds nest in the gutter above.'"
Gloria Hunniford told her: "It doesn’t matter, because if it brings you comfort about your sister, or if it brings me comfort about [her late daughter] Caron, it’s fine."
I believe in a higher being and spirituality things.
Ruth sadly lost her sister last year when Julia took her own life.
Sharing the devastating news to her social media pages at the time, Ruth said: "My lovely sis Julia has sadly died after a very long illness.
"My heart is completely broken.
"She was the kindest and most gentle soul and I will miss her forever.
"As I am sure you will appreciate I need to take time to grieve with my family. Thank you for your understanding."
Meanwhile, Ruth recently admitted she almost quit her TV career after Julia's death.
Speaking to Best magazine, the star said: "Following my sister Julia's death last June, I didn't feel I could ever go back to work again.
"It seemed wrong to be cheery on screen, when, inside, my heart was breaking.
"I just thought being 'happy' would be a lie - and disrespectful to my only sibling. I had no motivation or desire to be in the public eye."
