In recent beauty news, a so-called redhead confessed that she's actually a blonde (hint: she's one of the three women pictured). It got me thinking, how many other red-haired stars don't have, ahem, matching carpet and curtains?

Do you know who the only true redhead in this trio is? Is it "Mad Men's" Christina Hendricks (A) (Season 4 premiers in T minus two days …), "Sex and the City's" Cynthia Nixon (B) (see the "girls'" best and worst looks here), or starlet-turned-jailbird Lindsay Lohan (C)?
