Addis teen John Foster is through to the next round.

Louisiana singer and “American Idol” runner-up John Foster is Grand Ole Opry-bound.

Foster, 18, of Addis, made the announcement on Saturday night at the Cajun Country Jam Memorial Day Festival in Denham Springs. He was a last-minute addition to the weekend’s lineup, taking the stage with country singer-songwriter Craig Morgan.

“Tonight I had the pleasure of singing with Grand Ole Opry member Craig Morgan, and I’m incredibly honored to announce that I will make my Opry debut on Saturday, June 7,” he posted on Facebook after the show. “The first time I went to the Opry, I fought back tears because I was so overwhelmed with joy.

“As an amateur country music historian, there is no more significant place to my passion (country music) than the Grand Ole Opry. This has been my #1 dream ever since I started music, and now, because of your support, my dream will come true! I will NEVER be able to express my gratitude! Glory be to God!”

He will share the bill at the iconic Nashville, Tennessee, Opry that night with Opry members Bill Anderson, Old Crow Medicine Show, Mark Wills and more artists to be announced.

Foster, an LSU student, finished “Idol’s” 23rd season in second place, while Meridian, Mississippi’s Jamal Roberts took the title.
