Nicki Minaj has been making headlines for her feud with fellow “American Idol” judge Mariah Carey. But she shows the real reason she signed up for the talent competition in a new promo. The “Starships” rapper shares her passion for discovering new talent and explains her rise from the underground mixtape scene to becoming a worldwide superstar.

“I’ve been told no a billion times and I think it’s very important you have someone that knows what it’s like to be disappointed and have to try again, and that’s a big part of the audition process,” said Nicki.

The new season of “Idol” kicks off January 16 on Fox.
