Ariana Grande wouldn't be Ariana Grande without her sky-high, 2-foot-long (I'm rounding up...or am I?) ponytail. She's been rocking it pretty consistently since 2014 and has even commented that it's a "beauty is pain" situation. But don't forget Kate Beckinsale, who's made the high pony her own kind of signature as of late. The two also happen to share a history with "Saturday Night Live" cast member Pete Davidson...coincidence? It's a battle of the ponytails -- who will rise above the other?
