American Idol's eighth-season winner Kris Allen has another baby on the way.

Allen, 30, announced on Instagram Saturday his wife Katy O'Connell is pregnant with their second child.

Allen posted a photo of the couple's two-year-old son Oliver Neil stetched out in a cardboard box while wearing a T-shirt that reads "BIG Brother."

"#2016 is gonna be a good year!" the singer captioned the cute image.

O'Connell shared the same snapshot on her own Instagram account, writing, "Happy New Year everyone! So much for our family to look forward to in 2016!!!"

Oliver Neil was born in July 2013, about five years after his parents tied the knot in September 2008. Allen and O'Connell were high school sweethearts.

Allen starts his "Letting You In" tour in Birmingham, AL, in two months.
