Watch: Aretha Franklin's Granddaughter Auditions for 'American Idol'

Grace Franklin on "American Idol."

Even coming from a royal lineage is not a guarantee to get you a spot on "American Idol."

Grace Franklin, the 15-year-old granddaughter of the Queen of Soul, found that out the hard way when she auditioned for the long-running musical talent show on its 20th season premiere Sunday.

When asked how she came to stand before the judges, the teenager said, "My grandma is Aretha Franklin."

The statement elicited surprise from R&B legend Lionel Richie.

"Stop right there, that's your grandma!" exclaimed the "All Night Long" singer.

Unfortunately for young Grace, the elation would not last.

The music neophyte, who shared with the audience in a pre-taped segment before the audition, "I don't think I could fully grasp the fact that she [Franklin] was known worldwide, because to me she was always just grandma," sang two songs.

Her take on "Killing Me Softly," as popularized by Lauryn Hill of the Fugees, was called "a little sleepy and subdued" by country superstar and "Idol" judge Luke Bryan. Her next attempt at Franklin's hit "Ain't No Way," was agreed to be more "in her lane" by the judges, but that was not enough to sway Bryan and Richie who voted for her not to advance.

Bryan sternly declared, "For right now I'm a no," before Richie took a slightly gentler approach on the deciding vote.

"Grace Franklin, I love you and I think the best thing for you in life is to take a shot at going backwards," he said. "Go back and get a running start and come at this again."

Perry, who voted her through to the show's next round, stormed off the stage following the decision.

As she exited the judges' chambers the "Teenage Dream" singer said, "She's got stardust on her! There's something wrong with your ears. Y'all are insane!"

Richie, however, was not done. He rose from his seat to address Grace directly and told her, "Trust me! If you go and come back and put the shyness behind you and the voice in front of you, you're going to be something amazing and I don't want to be the one to make you tip over and fall at this stage," and gave her a hug.
