The group then headed into REHAB where they were joined by Corey Gamble. Resident DJ Loczi dropped Bieber’s song, “Wait For A Minute,” as he and a friend ran back and forth across the stage to scope out the crowd.

Bieber got on the mic to let everyone know that he was cheering for Floyd “Money” Mayweather before performing his latest, chart-topping single, “Where Are Ü Now.”

Throughout the entire afternoon, Bieber was seen with a smile on his face while he danced on stage, took pictures with guests, shook hands with his fans and sprayed champagne showers over the partygoers.

Around 4 p.m., rappers Flo Rida and Red Café showed up to the dayclub. Guests were in for a surprise as Flo Rida, who helped celebrate REHAB’s grand opening last week, did an impromptu performance to “G.D.F.R” and “Low.”
