Something probably looked a little familiar to Beyoncé last night as she walked the Golden Globes red carpet.

Oh, right, House's Olivia Wilde was wearing the same Reem Acra gown the chanteuse wore a month ago at the 40 Principal Awards in Madrid.

(Good thing B's alter ego, Sasha Fierce, wasn't around—who knows what could've gone down in the presence of the claw.)

Olivia looked sweet and stunning in her ethereal lavendar confection with sparkly Van Cleef & Arpels brooch, while Beyoncé went for high drama in the black version back in December.

This one's a toughie, because both gals are obvs gorgeous. But take a stand and let us know who you think wore this dress best!
