"American Idol" alum Josh Gracin is going to be a father of five.
Gracin is already dad to three daughters, Briana Marie, 17, Gabriella Ann, 12, and Isabella Sophia, 10, and a son, Landon Joshua, 13, from a previous relationship.
The new baby will be his first child with Katie.
"Baby Luka Gracin coming 2020, Katie and I couldn't be more excited!" he wrote.
Katie confirmed the news in a post on her own account."Josh and I are SO excited to announce we are expecting our first! We can't wait to meet our baby boy! We've even had the name picked out since before being pregnant," she wrote.
Gracin told People they chose the name Luka to honor his family's heritage.
"Luka represents my father's Croatian heritage and Italian blood," he added. "Prayers were truly answered!"
Gracin and Katie married in Nashville, Tenn., in May 2017. Katie marked their two-year wedding anniversary in May with a sweet post on Instagram.
"You're my forever wedding date (even if you always have shows booked lol), my Disney adventurer, my ride or die, the half that makes me whole, and all of the other cliches," she wrote.
"This year is going to be our greatest adventure yet. I love you so much."
Gracin came to fame during "American Idol" Season 2.
