Nicki Minaj believes baring her breasts would secure the win should she have a sing-off with Mariah Carey.

The pair are judges together on TV singing competition American Idol.

Nicki has a winning foolproof formula should Mariah ever compete with her hypothetically in a competition similar to that on Idol.

“Oh, I wouldn't sing,” she joked to Extra.

“I would just stand there and flash my boobs.”

Nicki has partnered with MAC Cosmetics to create a VIVA Glam line of makeup.

The musician is known for her eccentric style and flamboyant face paint.

She assures that although she enjoys embellishing her look, underneath it all she is completely natural.

“I’ve never had surgery on my face,” she explained.

“When people see my makeup they think all types of crazy things that I'm doing to my skin, but it's makeup.”

Nicki claims that she will tone down her attire a bit in 2013.

The 30-year-old singer is ready to embrace a more mature appearance.

“It's a bit more grown and sexy and like... less is more,” she said.

“[I’ll wear a] scarf on my head, t-shirt, Uggs.”
