Pop star Justin Bieber celebrated his father's engagement to his longtime girlfriend at a private Toronto art event that featured an actual Bengal tiger.
Jeremy popped the question to his girlfriend, Chelsey Rebelow, in February while they were vacationing in St Barts.
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", reported People magazine.
Bieber, 22, spent time at the party petting the tiger - a moment he later Instagrammed - and hanging out in the Batmobile and the superheroes, as well as with his father.
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.
