Iain Stirling, who hosted the hit U.K. reality series with Flack, paid a social media tribute to his friend on Instagram.
Said Whitmore: "Her family played it at her funeral last year and a very good friend of the show, musician Imelda May, has kindly recorded a version just for us.
Whitmore — who is currently expecting her first child — posted some poignant lyrics from the song on Monday, followed by an image of her enjoying some good times with Flack.
Others who honored Flack include her manager Nathan Charles Smith, who posted an Instagram Story showing the Love Island host preparing for a photoshoot inside a rusting camper van.
Talking to BBC Radio 4 Woman's Hour on Monday, friend Ophelia Lovibond opened up about her own memories of Flack and spoke movingly about the impact of the "suddenness" of her death.
I think something that was very interesting to discover was that the grief feels different because it was a complete shock, there was absolutely no way of getting used to the idea or visiting someone [in] hospital.
