If you're auditioning Thursday in New Orleans for ABC's reboot of "American Idol," take some advice: Don't be afraid.

"In an arena where you're competing against the best of the best, it's easy to let fear rush in. Do not let this happen," says Ethel native Megan Miller, who auditioned and advanced to the Hollywood rounds in seasons 12 and 13 of the reality singing competition series formerly on FOX.

Although Miller didn't become a finalist and make it on the live shows either time, the experience was a springboard toward a singing career, which she's pursuing in Nashville.

"The contestants that do well are the ones that are relaxed, confident in their gift they've been given and show up to entertain the judges, not just prove their worth," Miller says.

The 27-year-old LSU graduate also advises hopefuls not to pay attention to other people.

"Although they may be great, so are you. Everyone has their unique qualities, and at the end of the day, you have to be yourself because you never know what they are looking for," she says. "If you are not chosen, remember that they are casting, not measuring how talented you are. This could always play in your favor. So be confident and be strong."

The auditions at the Ernest N. Morial Convention Center are the last preliminary tryouts scheduled for "Idol," which premieres in 2018 on its new network. Follow-up auditions with "Idol's" new judges begin in October. So far, the show has nailed down singer Katy Perry as a judge for a reportedly whopping $25 million. Ryan Seacrest, host for all previous seasons of FOX's once-formidable franchise, has also signed on. The presumedly two remaining judges' chairs have yet to be filled.

Those planning to audition in New Orleans and who haven't registered can do so online at http://abc.go.com/shows/american-idol/auditions or register that morning at the center, 900 Convention Center Blvd. Signup is expected to start no later than 9 a.m. and continues throughout the day. 

Prospective contestants must be between 15 and 28 years old as of June 11, 2017, and a legal resident with the unrestricted right to work in the U.S. Those unable to make the in-person auditions can submit an audition video online at the website listed above.
