Cheeky

In writing news, I just received the line-edited manuscript from my editor. Apparently I am rather limited in my ability to convey embarrassment. Several times in my book I describe the main character feeling heat rising into her cheeks. Each time my editor oh-so-gently penciled the words "hot cheeks" in the margin, and I came up with new and varied ways of describing humiliation.

However, now, I can't stop thinking that hot cheeks sounds like a rather frisky nickname, as in
"How do you like my book, hot cheeks?"

Could I say that to a reviewer, or would that be cheeky? (I know, but I couldn't resist.)
