Danica Patrick didn’t hire an executive charter jet service recently to avoid brandishing one of the “Fifty Shades of Grey” novels while flying commercial. But it might be an ancillary benefit.

Since Patrick admitted on Twitter that she had, to her disappointment, reached the end of the first of E.L. James’ best-selling mainstream erotica trilogy, the NASCAR Nationwide series driver said she has been inundated by followers advising her how to indulge in the titillating tome more discreetly.

“I don’t think I’ve ever had so much response, continuously, from people about these books and their opinion and telling me to get devices so that they don’t see the book I’m holding,” Patrick told espnW.com. “What I wanted to say is, it’s not the book that I’m holding that I’m so embarrassed of, it’s the content of the book. And if somebody has read it, they know exactly what it says. That’s embarrassing. It’s very interesting. Oh, yeah. There’s a lot of words I don’t understand in that book.”
