I can't wait for The X Factor to start, and I've just seen the first photos of Dannii Minogue and Cheryl Cole in Glasgow after a round of auditions. Dannii's never been shy about changing up her look or wearing heavy metallic makeup. She's fun to watch onscreen because she's got a strong opinion and she's bold with her beauty choices. After looking back at the past couple of months however, it's Dannii's hair that's really caught my attention. Out of these four recent haircuts below, which length do you find the most flattering on Ms. Minogue?
