Who will be one of the last to take the title of “American Idol”?

Wednesday’s finale comes only days after Fox announced that next season will be the last for the once-dominant music competition.

So will it be the guitar-strumming Nick Fradiani, of Guilford, Connecticut? White House, Tennessee’s Clark Beckham, who comes from a gospel-singing family? Or the Jersey girl who just goes by Jax?

For a while, Louisiana fans thought one of their own could take it all, as New Orleans’ Quentin Alexander progressed to the top six on the Fox show’s 14th season before being sent home. But Alexander’s back in Los Angeles now rehearsing with the other “Idol” finalists for Wednesday’s finale night, known for its surprise pairings of “Idols” and their favorite singers in once-in-a-lifetime performances.

“I am extremely excited for that (finale night),” Alexander, 21, said after his exit from the show. “You know we go into it looking forward to that big-bang ending, and I’m excited to see who’s there at the finish line, because we’ve built such a strong bond. It’s like a family, and I’m going to be proud of whoever it is.

“If I had a chance to perform with anyone, of course I would definitely choose, like, Lenny Kravtiz or someone like Erykah Badu or Lorde. Really Annie Lennox, with doing ‘I Put a Spell on You,’ I would love to share that moment with her because she is such a monster on that song.”

Lennox stole the show at this year’s Grammys with her performance of the Screamin’ Jay Hawkins classic. She also covers the song on her latest album, “Nostalgia.”

Fans can expect more edgy attire from Alexander on finale night, as throughout the season. The retail store manager was known as much for his soulful voice as for his fashion sense.

He attributes his original style — including furry coats, head scarves and leather vests — to having to shop thrift stores for his look.

Alexander is now working on his own clothing line, he said, as well as on short films that incorporate his music.

Meanwhile, Fradiani, Beckham and Jax are working out their last songs, hoping to be one of the two who will sing one more time for “Idol” voters Tuesday night and move one step closer to that “Idol” title.

The network said next season will be the 15th and final for the talent show, which is credited with changing television competition shows and forging the way to new hits like NBC’s “The Voice.” The show, hosted by Ryan Seacrest, started in the summer of 2002, but has been losing audience in recent years. Fox is planning a major revamp to its lineup.
