The ghost of Whitney Houston might have haunted the rooftop NBCUniversal Golden Globes party Sunday night. Partygoers who got goose bumps on the fourth floor of the Beverly Hilton probably didn’t realize that NBC was using some rooms surrounding the former Room 434 — where the pop diva, 48, died less than a year ago in February on the eve of the Grammys — as bathrooms for VIP guests such as Anne Hathaway, Jimmy Fallon, Lorne Michaels and Jessica Chastain, who arrived clutching her trophy after winning for best actress in a drama. Room 434, where Houston likely suffered a cocaine-induced “cardiac event” before falling into the bath according to the coroner, no longer has a number. “It’s not in our inventory,” a hotel exec told Page Six. The exec wouldn’t confirm reports that staff, seen going in and out during the party, now use it for “storage.”
