Nicki Minaj killed two birds with one ridiculously expensive stone — a $1700 couture jersey with the words “Pervert 17” on it — which looks like a direct shot at her label mate Tyga . Tyga and Nicki have had beef since last year when he said he was pissed he had to work with Nicki and Drake … just because they’re all signed to Young Money . We’d say that’s a stupid amount of money to spend just for a little revenge, but fact is — that’s just a stupid amount of money to spend on clothing, period. Considering her bad blood with Tyga … a lot of people think it’s also not-so-subtle commentary about his 17-year-old girlfriend, Kylie Jenner.
