Kelly Clarkson reveals pregnancy shock

Kelly Clarkson feels like her new baby will be the "yin" to 14-month-old daughter River's yang.

The 33-year-old singer told the audience at her Los Angeles concert on Wednesday night that she's expecting her second child with husband Brandon Blackstock.

But in an interview just months before, Kelly admitted she was feeling a bit apprehensive about further expanding her family.

"I'm frightened to have another one," Kelly told People back in February. "I want another one — like in a couple years."

Kelly is also stepmother to Brandon's two children. But she admits it's River's sweet nature and perfect personality that made her question whether or not she was ready for another child.

"I'm just a little frightened because she's so perfect," Kelly added. "I feel like something horrible's gonna come out of me. Because she's so great — like, the yin to her yang.

"But I won't put that out there. I'm gonna project happiness."

Prior to announcing her pregnancy news, Kelly struggled to control her emotions as she introduced her song Piece By Piece.

"I was totally not planning on announcing this, but I'm pregnant. I'm having a really hard time," she told the crowd at Los Angeles' Staples Center before breaking down in tears.

The song is dually an ode to her own father, as well as commending Brandon on being a good dad.

"I'm gonna nail the sh*t out of this song. That was not how I wanted to announce that … I hate this song right now," she joked as she wiped away tears. "My make-up artist is backstage hating me right now. I just don't want you to think I'm on pills or drunk."
