Kelly Clarkson and her husband, Brandon Blackstock, are expecting a baby girl.

The singer tweeted the news on Monday.

"We just found out we're having a girl officially!" the singer wrote. "I knew it! Only a girl could cause this much drama with all this vomiting ha!"

Clarkson has been surprisingly candid about her morning sickness woes during her pregnancy, often posting about vomiting on her twitter account.

"Ladies if u r pregnant & sick as a dog trust me when I say the one thing u will keep down might just be 'baked potatoes' #godblesspotatoes," she wrote on Jan. 12.

The baked potatoes tweet came just two days after the Breakaway singer appeared to be doing better with her pregnancy symptoms.

"Didn't throw up once from pregnancy while walking my dogs #smallvictory #TMI #hashtag," she captioned a photo of the two leashed dog walking down the street.

Twitter has not been the only platform where the singer has shared her morning sickness troubles.

Clarkson also talked about her sickness when she guest starred on Ellen on Dec. 6.

"I vomit a good dozen times a day it's like bad. I vomited before coming out here," the singer said. "I'm not even kidding, it's so bad. It's so bad. It's, like, so gross."

Clarkson has also revealed on social media that her potential due date is sometime this summer.

"In less than 6 months I'm gonna have a baby...for whatever reason it's really hitting me tonight. Wow. Gonna be the coolest kid ever," she tweeted Jan.9.

Clarkson married Blackstock on October 20, 2013. He is Blake Shelton's talent manager.

This will be the first child for Clarkson and the third for Blackstock. He has two children from a previous marriage.
