In addition to the four-legged animal at the party over the weekend, other attendees included costumed superheroes such as Iron Man, Wonder Woman, among others.
Former boxing heavyweight Lennox Lewis and Canadian opera singer Meghan Lindsay were also present and performed during the affair.
TMZ reports that the Biebs also performed at the party and played the piano. He also posted photos on Instagram of him hanging out in the Batmobile, and the guests dressed as superheroes.
Meanwhile, Jeremy Bieber popped the question to his girlfriend back in February while they were on a vacation in St. Barts. The proposal was later uploaded on YouTube.
The 40-year-old Jeremy was seen ecstatic while showing the ring and popping the question while his 28-year-old girlfriend became very emotional after accepting the proposal.
During his dad’s engagement party, the Biebs also debuted his new hair. After receiving tons of backlash for rocking blond locks, the “I’ll Show You” singer has shaved all his hair off, much to the delight of his fans.
The Canadian heartthrob sported ripped jeans and a polka dot buttoned-up short. He was photographed talking to fellow guests and posed for a photo with Lennox Lewis. He was also seen posing for a photo with his dad and his beaming bride-to-be.
