“So about that project I've been working on!! We are over the moon about expecting our first little bundle of joy!!” she wrote with a photo of herself and her very pregnant belly.
She has been married to Andrew Robert Sandubrae since 2010.
Her big sister Shelley already has a daughter and a son, so Krystal's baby will be Toby’s third grandchild.
Krystal began her recording career in 2004 when she joined her dad on a remake of "Mockingbird" as a track on his Greatest Hits 2 album. She released her debut album,
Whiskey & Lace, in 2013 and charted her first solo single, “Daddy Dance With Me,” the same year.
Krystal had tweeted a few days ago that she had an exciting announcement about her "current project."
Her dad hasn't tweeted about the news yet, but he did tweet on Wednesday that his Good Times & Pick Up Lines tour kicks off in a month. Maybe if Krystal has had the baby by then, he'll bring them out on the road for a show or two.
