Billboard hosted its second annual Grammy after-party at the London Hotel rooftop Sunday night (Jan. 26), sponsored by Citi and Bud Light Platinum.
Though Prince didn't make a return appearance this year, artists like Darren Criss, Richard Marx, Sirah and Mike Posner all worked the carpet, while guests like Citi's Jennifer Breithaupt, Pepsi's Javier Farfan, ICM's Marsha Vlasic, Next Big Sound's Alex White and others rubbed shoulders.
The party scene shifted from poolside cabanas, where execs from Citi, Bud Light Platinum and Billboard parent company Guggenheim Partners all mingled, to a packed dancefloor where Win Records founder Sean Glass and Radio 1's Pete Tong traded DJ duties.
In addition to the strong music contingent, actresses like Ariel Winter ("Modern Family") and Andrea Bowen ("Desperate Housewives," "G.B.F.") were spotted among the crowd as well.
Many guests were overheard buzzing about the performances from Imagine Dragons, Macklemore and Daft Punk, the latter of whose surprise after-party downtown was the most coveted destination on party-hoppers' itinerary (most settled for Republic's packed celebration at 1Oak just a few blocks down the Strip).
