Hot or Not? The Two Tone Ponytail

There has been a trend slowly arising in the fashion world and celebrity world recently. Many magazines have featured editorials with models with two tone ponytails, and now the hottest celebrities of the moment have caught on to the trend, and are leading the way to make it mainstream. Based on the following photographs, what do you think? Its this trend on-fire hot, or totally not?

Lady Gaga's Twitter profile pic. I like it, but I like more of a contrast with this style.

What do you guys think?

Is this trend HOT or NOT?
