Rocky made a memorable entrance on Saturday night.Wearing dark sunglasses, walnut-sized diamond earrings and a T-shirt with a bulletproof vest printed on it, the rapper, style maven and professional wife guy began his headlining set at this weekend’s Rolling Loud California festival by descending down a cable hanging from a helicopter suspended over the show’s main stage as his song “ASAP Forever” blared across the grounds of Inglewood’s Hollywood Park.
