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.

Bieber leaves New Zealand today after cramming in a bungy jump off Auckland's Harbour Bridge, and appearing at a "Bieber-que" hosted by radio station ZM.
He appeared at Rae Sremmurd's show after performing an intimate showcase for around 150 fans, and recording interviews with TV3's Paul Henry and Story's Heather du Plessis-Allan.
The promoter of the Rae Sremmurd show, Paint It Gold, released a statement saying:
"Rae Sremmurd have been in New Zealand for several days ahead of their sold-out first New Zealand show at the Studio last night. Their friend Justin Bieber was also in town on a promotional tour, and decided to drop into the show to catch up with his friends. Justin [joined] them on stage for several Rae Sremmurd numbers and a rendition of his hew song What Do You Mean."
