Triston Harper is saying howdy to fatherhood at age 17.

The American Idol alum became dad after he and his wife Paris Reed of less than a year welcomed their first baby together, according to his family.

“Everybody my Grand Baby has made her Grand Entrance,” Triston’s mom Hattie M. Sullivan announced on Facebook June 23. “Weighing a solid 6lbs and 6 ounces, Brenley Lichelle Harper has now arrived on the scene and she ain’t here to play.”

The matriarch added of her granddaughter, “She’s already in boss mode!!!!! Feed me, Change me, Cut that bright light out. Yes ma’am whatever you want G MA is gonna make it happen!”

Triston—who competed on the season 22 of American Idol last year—announced his marriage to Paris in November, changing his Facebook relationship status with a cheeky caption to fans, reading, “[I’ve] got big news harpies.”

Two days later, Triston’s mom revealed that the country singer’s new wife was pregnant.
