My Strange Addiction

Bertha loves nail polish, but isn't addicted to manis and pedis.

On Sunday's My Strange Addiction (10/9c, TLC), the 23-year-old reveals that she likes to hit the bottle... the nail polish bottle that is. Bertha got her first craving to drink the colorful stuff five years ago when she couldn't resist the smell in a salon.

She even has different ways of enjoying this unique beverage: sipping, taking shots or licking it from the tiny brush. What's next? A flaming nail polish cocktail?
