Rob Gronkowski says he's only read 80 percent of his autobiography

New England Patriots tight end Rob Gronkowski is now a published author thanks to the release of his autobiography, "It's Good To Be Gronk." But that doesn't mean he's actually read it.

During an interview with Maria Menounos of SiriusXM on Monday, Gronkowski admitted that he's only read 80 percent of his book.

"I'm not going to lie about it. That's what the book is – it's all truthful in there. It's no sugarcoating or anything. It doesn't make my image look good, it's no false image in there," Gronkowski said.

"I ain't going to lie either, I only read like 80 percent of it, but I know what better parts were and everything; what it's all about. It was a quick deadline. I couldn't get to it all."

To be fair, Gronkowski has had a lot on his table this offseason. He released a Dunkin' Donuts-themed album, spiked pineapples in Las Vegas and, most recently, appeared on "Family Feud."
