Exclusive video: Justin Bieber's booze bender ends with a performance at LIV

Justin Bieber was seen checking in Tuesday The Villa Casa Casuarina (formerly the Versace Mansion) before heading to WALL where he gave a surprise performance. Bieber left that club with fifty--yep, 50 people-- and brought them back with him, partying until 8 a.m. Wednesday. The Biebs lounged it off all day at the pool before heading to sceney steakhouse Prime 112 for lunch around 3:30 p.m. A waiter said  Bieber "seemed to be intoxicated, most likely from the night before." Ya think?  Following lunch he went back to Casa Casuarina to nap before hitting LIV Nightclub, where he showed up just after midnight and spent the majority of the evening singing along to his songs and dancing to them from the DJ booth.
