Both Mel B. (of Spice Girl fame) and Rihanna took a risk recently with new 'dos, but only one managed to walk the fine line between fabulous and fugly.

While Rihanna took a basic cropped cut and added texture and volume, Mel B. looked as though she'd stepped off the set of a sci-fi film with a faux-hawk updo. On the bright side, her stylist was able to distract us from that outfit, which was quite the challenge in itself...

What do you think, are either of these looks a hit (or are both a miss!)?
