The American Idol winner previously announced she is expecting her second baby with Brandon onstage during one of her concerts in August. After holding back tears while introducing her next song, "Piece By Piece," Kelly surprisingly exclaimed, "I was not planning on announcing this, but… I’m totally pregnant. I’m having a really hard time."
