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.
