Carrie shared some big news with her fans Wednesday.
(Undated) -- Carrie Underwood and husband Mike Fisher are expecting their second child.
The country music superstar revealed the news yesterday in an online video.
Carrie first announced her upcoming tour, but then the camera zoomed out, revealing balloons that read "baby."
It's also speculated that she's having a girl since almost everything in the video was pink, including Carrie's jacket.
Carrie and Mike welcomed their first child, Isaiah, in February 2015.
