Some of the UK's best-known YouTubers are to present a four-hour livestream session on Thursday offering tips on staying upbeat during lockdown, while raising money for the NHS.
Saffron Barker, Lady Leshurr, Big Narstie and Anastasia Kingsnorth are among those taking part.
Viewers will be encouraged to donate to the NHS Charities Together campaign.
The YouTubers will also perform and complete challenges and talk about how they are coping with lockdown.
Luke Hyams, head of YouTube Originals EMEA, spoke about the importance of bringing people together with Stream #WithMe.
He said: "Life in isolation brings both difficult challenges and moments of joy. We hope this show brings the latter."
Each hour will have a new host, with other performers "tag-teaming" their way through the show, with "lockdown tips" on "how to keep entertained, upbeat, and active".
Creators and stars will also be presented with two mystery box challenges that showcase things for viewers to try at home.
Kevin Batchelor, co-founder of the show's production company Electric Robin, said: "Because we are in isolation, this livestream is a real technical challenge - combining 12 different live locations together using up to 60 different cameras."
He added they hope it will "help bring some light into homes as we navigate these unprecedented times, while also helping raise money for those on the frontline".
