The two-time Olympian champion will interact with famous guests and participate in the current and engaging conversations on the award-winning midday program in front of a brand-new live audience, which also resumed this week.
Dame Kelly Holmes said:
"I am extremely excited about joining Loose Women. Having met a few of the panellists recently, I know that the shows will be full of energy, smiles, tears and lots of laughs.
"I hope I can bring my energy to the show and will be up for doing any mad experiences they throw at me!"
She added, "It will be so different to anything I have done before in my career, but now that I have found my authentic voice since the airing of my documentary, Kelly Holmes: Being Me, I will join in on many conversations that I felt I never could before."
