Kelly Clarkson has revealed that she and husband Brandon Blackstock are expecting a baby girl.
The singer - who announced her pregnancy in November - shared the news with her fans on Twitter.
She wrote: "We just found out we're having a girl officially!"
Clarkson added that she had already suspected that she was having a daughter.
"I knew it!" she said. "Only a girl could cause this much drama with all this vomiting ha!"
The American Idol winner has previously spoken of her struggle with morning sickness, describing pregnancy as "so gross".
"I vomit a good dozen times a day," she said during an appearance on The Ellen DeGeneres Show.
She continued: "You're not attractive when you're pregnant. Everybody tells you [that] you glow and your hair is pretty and your nails are pretty.
"That's total crap. My nails are short, my hair still falls out like it's not all lush and beautiful, and I have no glow.
"Unless it's, like, something left over from a bad throw up. It's horrible."
The news of Clarkson's pregnancy came just a month after she and Blackstock married in Walland, Tennessee in October.
Shortly before the wedding, Clarkson joked about her desire to become pregnant before Christmas.
The singer is a stepmother to Blackstock's two children from a prior relationship.
