Justin Bieber and the Duke of Cambridge were among famous faces who took part in this year’s Red Nose Day on BBC One.
The Canadian singer gave this year’s Comic Relief charity fundraiser an exclusive performance of his latest song Hold On.
Prince William thanked the public for its “compassion and generosity”.
Comic Relief raised a total of £45,938,942 on the night to help tackle hunger, homelessness, domestic abuse and mental health stigma.
Speaking about mental health in a recorded video message, the duke said: “This is a subject that is very close to my heart and it’s wonderful to know that your support tonight will make sure that there is help at hand when things become too much for people.”
Bieber – who released his album, Justice, earlier on Friday – asked viewers who could to donate to “help those who need it most”.
Other stars to take part included Daniel Craig and Catherine Tate.
Craig’s James Bond came face-to-face with Tate’s Nan character in a sketch that saw Nan cleaning an office in MI6 before accidentally video-calling 007.
