The very last audition on tonight's 'American Idol' (Jan. 22) was Miley Cyrus look-alike Marrialle Sellars, who sang Bruno Mars' 'Grenade.'

She was pushed at a young age by her father to be a singer and musician, but in 2008 he passed away -- and now she's on 'Idol' to put everything he taught her to use.

Despite only being 17 years old, Sellars immediately impressed the judges with her style and her singing prowess.

Without even discussing it, all three passed her to Hollywood. Not only that, but she came out with multiple golden tickets.
