Superstar Kelly Clarkson has announced the birth of her second baby. 

The 'American Idol' alum told her Twitter followers this afternoon (April 14) that she has now welcomed a son into the world. She tweeted: "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!"

She already has a daughter, named River Rose, and last month told Australia's KIIS FM that once she gives birth to her second child she will be done having babies because pregnancy is "rough" on her:

"Oh, no, we are done. Oh good Lord, yes, I can't be pregnant again. This will be our number four total, so we're good... Honestly, the first one was really rough, and I was like, 'Oh, it can't happen again,' and no, it happened, like, way worse this time."
