The Dixie Chicks' Natalie Maines is no stranger to saying controversial things. Remember a certain overseas criticism of then-President Bush that effectively destroyed the Chicks' country career?

Here's what Natalie tweeted during the Jason Aldean-Kelly Clarkson "Don't You Wanna Stay" duet on the Grammys: "Well the good thing about his mic going out is suddenly the song got a lot more in tune;)"

And Natalie, who conceded she hasn't kept up with country music recently, then showed she didn't even know who Jason was: "By 'he' I mean whoever the guy was singing with Kelly Clarkson."

Dozens of Natalie's own fans called the comments mean. And while Natalie seemed to back off some afterward, saying that every performer can have a bad night, Natalie went on to add that she's not so fond of country music.

"Oh I'm sorry I've disappointed you," she tweeted to a 20-year-old fan named Michelle. "As far as you thinking I was ever some lover of country music, you just thought wrong. I've got a handful of country people I like, but I've always been very open about my musical preferences. I liked the Dixie Chicks.

"I didn't know I had to sign on for everything country. Music's subjective. There shouldn't be rules. Different strokes for different folks. All the best, N."

One country stroke Natalie does like: Taylor Swift.

"Haven't seen anybody make the banjo look sexy since [fellow Dixie Chick] Emily Robison. #goodjobtaylorswift," Natalie tweeted.
