Gronk finally spends that NFL money: 'Now I know why people got jewelry'

Rob Gronkowski is notoriously frugal when it comes to spending his NFL money, but he did treat himself to a luxury piece of jewelry recently.

The New England Patriots tight end, who earned $10.18 million last season, showed off his new diamond chain while appearing on the Uninterrupted series "Kneading Dough."

"When I signed my incentive deal last year, my friend had a chain, and I was like, 'Dang, man, that's a nice chain.' I'd never had jewelry in my life ... So then in the back of my head, I said, if I hit all my incentives, if I do everything I need to do, get all my bonuses, put all the work in, I gotta finally treat myself," Gronkowski said.

"It's been eight years, I haven't really bought anything in my career, don't really have anything luxury like that. So last week, I finally went out and bought myself a chain. I got it on right now. It's right here, baby. I finally got one, and I love this puppy. This is my first thing I've ever gotten, and I love it. It feels good. Now I know why people got jewelry. Now I understand why."

In his 2015 memoir "It's Good to be Gronk," Gronkowski revealed he hadn't touched his NFL salary, instead living off his endorsement deals.

"To this day, I still haven't touched one dime of my signing bonus or NFL contract money," he wrote. "I live off my marketing money and haven't blown it on any big-money expensive cars, expensive jewelry or tattoos and still wear my favorite pair of jeans from high school."
