Kelly Clarkson and her husband Brandon Blackstock welcomed baby No. 2 on Tuesday, April 12.

Clarkson took to Twitter on Thursday to announce the birth of their baby boy who they named Remington Alexander Blackstock.

As we previously reported, the 33-year-old revealed the sex of her baby via Instagram in October.

“In other news, River’s gonna have a little baby brother ???? #itsaboy We’re so excited!” she captioned a pic of her daughter on a slide.

Clarkson initially told a crowd that she was pregnant after getting emotional during a show last August.

The first-ever American Idol winner and her hubby, whose father was married to country superstar Reba McEntire, tied the knot in 2013. Blackstock has two other children from a previous relationship.
