New York – Rihanna snubed former friend Naomi Campbell in tense New York Fashion Week (NYFW) run-in. Rihanna walked past the supermodel without acknowledging her at the Alaïa runway show. Naomi offered polite smile but the pop icon appeared to ignore her former friend. It is not the first time the duo has clashed publicly. In 2014, at the British Fashion Awards, Naomi was caught on camera clutching the FENTY beauty owner and saying something to her, only for the singer to shoot her a cold glare in return.
