Rob Gronkowski has only read 80 percent of his own book

Rob Gronkowski is currently promoting his book, "It’s Good To Be Gronk," (he appeared on "Celebrity Family Feud" last night) which comes out Tuesday. During an interview with Maria Menounos for SiriusXM, Gronk kept things real by admitting that he didn’t even read his own book. "I ain’t gonna lie to you," the Pats tight end told Menounos. "I only read like 80 percent of it. But I know what the other parts were and everything and what it was all about." Considering he wrote the book, we’re glad Gronk knew what it was about.
