Justin Bieber actually spent his dad's engagement to his longtime girlfriend party with an actual Royal Bengal Tiger.
The engagement party appears to have been held at a private art show, simultaneous to an event called the 'Nyotaimori Celebrating Life Love And Art,' reports People magazine.
'Nyotaimori' refers to the Japanese practice of serving sushi off the bodies of naked women.
The 22-year-old popstar spent time at the party petting the tiger which he Instagrammed a moment later.
Other attendees included costumed superheroes such as Iron Man and Wonder Woman, former boxing heavyweight Lennox Lewis and Canadian opera singer Meghan Lindsay, who performed.
