Photos: Miserable looking Justin Bieber attends dad Jeremy's bizarre engagement party

Justin Bieber joined his dad Jeremy in Toronto on Saturday for his engagement party. However, the 22-year-old, who only days ago shaved off his blonde dreadlocks, failed to crack a smile in any of the photos taken at what was supposed to be a happy occasion.

The Canadian singer looked downright miserable as he posed for pictures. Not even a tiger brought along for entertainment, not even the presence of Iron Man or a gender swapped Captain America could cheer him up. His mood sha did not dull his dad's high spirits who was beaming with his blushing bride to be, 28-year-old Chelsea Rebelo. See all the pics below.
