Justin Bieber has certainly improved with his attitude over the years, but he may have ruined it by disrespecting Prince. A guitar player by the name of Andrew Watt wrote a beautiful little tribute to Prince on his Instagram, and in the tribute he called Prince "the last of the great living performers".

Bieber then allegedly left a remark which set off a firestorm on Wyatt's Instagram page, saying: "Well not the last greatest living performer."

The comment has since been deleted but according to Gossip Cop, Bieber's PR team insists the comment was "fabricated". The singer has yet to address the matter on Twitter. Gossip Cop claimed it could not locate any supporting evidence that Biebs made the comment himself.
