Manuel appreciates Damiano's pole dance, and the boy decides to make his coach happy
Manuel Agnelli was Måneskin's coach at X Factor, and he was the one who had the brilliant idea of making Damiano dance on a pole. Unfortunately, at that time he hadn't grown a beard yet.
For other indications, read the series description (it's both in italian and english).
The first picture is real (he SERIOUSLY said that).
The second isn't (for what we know, at least).
