S Club 7 star Paul Cattermole shared a Eurovision Song Contest Comic Relief skit a few weeks before his shocking death this week.
The singer died at the age of 46 just weeks after S Club 7 revealed their plans for a reunion tour.
S Club 7 shared a statement about how "devastated" they are over the loss.
In the middle of March, Paul shared his last post, which featured a Red Nose Day skit about searching for the UK's next Eurovision entry.
Paul posted a short clip of the skit that saw him and other stars come together to compete for a place in the song contest.
He appeared in the charity video with Graham Norton, Sam Ryder, Miranda Hart and Dermot O'Leary.
In the short clip, judges Graham, Lulu and Sam said they were on "the hunt" for the UK's next Eurovision entry.
Lulu quipped: "You won't believe who's trying to get in on the action."
The camera then cut to a host of stars walking into the audition room, including Paul and singer Fleur East.
Paul simply tagged S Club 7 as well as Red Nose Day's official Instagram page.
On Thursday, the pop singer was found dead at his home in Dorset and it was revealed that there were no suspicious circumstances around his death.
His S Club 7 bandmate and ex-girlfriend Hannah Spearritt is said to have "broke down" when she was told the news of his death.
His other bandmates have been left in "horror and disbelief".
A statement from the band reads: "We are truly devastated by the passing of our brother Paul. There are no words to describe the deep sadness and loss we all feel. We were so lucky to have had him in our lives and are thankful for the amazing memories we have.
"He will be so deeply missed by each and every one of us. We ask that you respect the privacy of his family and of the band at this time."
Tributes have been pouring in for the musician, including posts from Rylan Clark, Lizzie Cundy, Vernon Kay and Lorraine Kelly.
