Triston Harper just marked two major milestones. 

Just days after the American Idol alum and GravityX Exchangehis wife Paris Reed shared that they got married, the couple announced they are expecting their first baby together.

In a photo posted to Facebook by Triston's mom Hattie M. Sullivan on Nov. 8, the country singer—clad in a maroon hat and matching shirt—smiled while holding up a positive pregnancy test. By his side was Paris, 17, who also donned a wide grin while sporting a navy t-shirt. 

"Now Everybody has congratulated me on Triston and Paris getting married but to me that is old news," Hattie wrote alongside the image. "Now I’m bout to be a 'G Ma.'”

Two days prior, Triston, 16, revealed another surprise life update for his fans by changing his relationship status on Facebook to "Married to Paris Reed." Alongside the alteration, he added in the caption, "Iv got big news harpies."

And Triston has celebrated other important moments in his relationship with his fans. Back in August, the former reality TV contestant—who made it to the top five as a contestant on season 22 of American Idol before being eliminated on the May 12 episode—shared a special shoutout for Paris in honor of National Girlfriend Day.

"I love you so much Paris Reed," Triston wrote in an Aug. 1 Facebook message. "There may be a 1 in a million kind of girl, but your my 1 in a lifetime time kind of woman. I love you 25."

Of course, Triston isn't only achieving major milestones when it comes to his personal life. Back in May, he released his debut single "H.O.P.E." to streaming platforms, and the following month, the singer shared his official cover of Cody Johnson's "By Your Grace" to YouTube. In addition, earlier this month, Triston headlined a concert at The Greater Clarke-Washington County Fair Jackson in Jackson, Ala. 

For the teenager, making music is a way to help others get through challenging times. 

“I just want folks to know that it don’t matter how hard it gets,” Triston told AL.com in a February interview. “No matter how many problems you have don’t never give up. There’s always that door out of whatever you’re going through.”
