Justin Bieber Bizarre Engagement Party for Dad

5/1/2016 7:10 AM PDT

Jeremy Bieber had an artsy-fartsy party in Toronto, complete with tigers, superheros and the Biebs.

Jeremy and fiancee Chelsea Rebelo had their shindig at a massive, private Toronto estate.  The backdrop was an art show, but it felt more like a renaissance fair.

The pics are pretty cool, and of course Justin hit up the piano.
