It's a reality star versus an actress...

...in this who wore it best.

Heroes star Hayden Panettiere wore the purple strapless Zuhair Murad dress (he designed Miley's Oscar dress this year) to a Comic Con party back on July 25, while The Hills star Audrina Partridge wore it to the Teen Choice awards on August 9.

Hayden kept it simple, teaming her dress with black platform sandals, a black cocktail ring and a silver clutch bag.

Audrina chose clashing blue heels, a dark purple clutch, a silver necklace and bracelet set and simple stud earrings to compliment her dress.

So, who wore it best - Hayden or Audrina? Let us know below!
