Taking his shirt off, partying with a popular hip-hop group and swigging from what appears to be a bottle of Hennesy - Justin Bieber had quite the night last night.
The chart-topping pop star is in New Zealand on a whirlwind promotional trip, but Bieber hasn't let jet lag cut short his activities.
Photos and videos from hip-hop group Rae Sremmurd's Auckland show last night show Bieber showed up on stage, dancing, singing and drinking with the duo.
At one point, he pours what appears to be a $60-bottle of Hennessy out on stage; at another, he appears on the balcony above The Studio's main stage with his shirt off while surrounded by women.
