The 33-year-old Piece by Piece singer revealed on Twitter that they welcomed Remington Alexander Blackstock on April 12:
Our little baby boy has arrived!! Remington Alexander Blackstock was born 4/12/16 & he is healthy & we couldn’t be happier or more in love!
— Kelly Clarkson (@kelly_clarkson) April 14, 2016
She first announced her second pregnancy during her Los Angeles concert back in October, taking the crowd by surprise:
This is not how I wanted to announce [that I’m pregnant]. My makeup artist is backstage hating me. I didn’t want you to think I’m on pills or something. I would like to apologize to my husband. This was not planned. I’m just so hormonal. Everything is great, I haven’t vomited yet. That’s a win y’all.
Clarkson, American Idol‘s first winner, wed Blackstock in 2013 and together they welcomed their first child River Rose in June 2014.
