Celebrities including Drake, Sam Smith and the Jonas Brothers have taken part in the viral FaceApp challenge.
The mobile phone app takes a picture of a user’s face before showing them what they could look like as they age.
The filter adds wrinkles and grey hairs to selfies, generating a realistic-looking image.
Celebrities have shared their results on social media.
Canadian rapper Drake offered fans tickets to his music festival for the best picture caption on his post.
He captioned it: “Feeling cute might delete later.”
He said: “Last couple of weeks have really taken a toll on me.”
