The musician, known for his love of cannabis, said: “Ig (Instagram) down? Roll one and be productive.”
Actress and singer Bette Midler struck a more serious tone and pointed to the bullying often found on social media websites.
She said: “Facebook and Instagram are down. I guess that’s a good thing; a few hours respite for the poor kids who are bullied incessantly on those sites. All the adults in the room are hoping they stay down.”
