In an impromptu interview with TMZ, Cara Delevingne attributed animal behavior to her eyebrows. When asked about their upkeep, she replied:
They maintain themselves. They groom themselves. They're like a cat that licks her own fur.
Or like a self-cleaning oven, or the hand that washes the other. And if any human could ever have eyebrows with that kind of power, sure, why not, it could be Delevingne.
