BET Awards 2011 Arrivals: Nicki Minaj, Willow Smith, Justin Bieber And More (PHOTOS)

Pop stars were out in full force last night, to celebrate and (let’s face it) be celebrated at the 2011 BET Awards. As music’s hottest artists arrived at L.A.’s Shrine Auditorium, it was clear that the fashion trend of the night — from Bruno Mars’ Buddy Holly specs to Alicia Keys’ suspenders — was retro-inspired duds. Since Justin Bieber left his Saved By The Bell apparel at home, it Willow Smith representing the early 90s (and her dad) this time, by wearing a Fresh Prince t-shirt. As for Wiz Khalifa and Amber Rose, the couple ignored the paparazzi by smooching on the red carpet.
