In addition to learning absolutely “nothing” from John Mayer or Nick Lachey, Jessica Simpson takes a stand in the latest issue of Allure magazine.

“He didn’t make me go brunette,” Simpson tells Allure, referring to her darker hairdo in 2006 and 2007. “John doesn’t get credit for making me brunette. He’d like to think so, but he doesn’t deserve the credit.”

While Simpson’s interview was conducted prior to John Mayer’s controversial Playboy interview, Simpson’s cover story in Allure is interesting in that she covers her break-ups and life being single.

“I’m on my own, and it’s nice.”
