Kelly Clarkson looks positively glowing!

The 33-year-old pregnant singer took to Instagram on Thursday, Feb. 25 to share a rare photo of her growing baby bump — and we think Kelly looks amazing in the pic!

"I'm baaaack! See y'all tonight! #KellyOnIdol," Kelly captioned the snapshot of herself seemingly backstage at the American Idol studios. The "Stronger" songstress was the long-running reality competition's Season 1 winner back in September 2002.

Kelly previously announced she is expecting her second baby with husband Brandon Blackstock onstage during one of her concerts in August 2015. 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."
