Kelly Clarkson announced her pregnancy back in August during one of her concerts, and the "Heartbeat Song" hitmaker displayed the baby bump at the red carpet event for the Citizen Watch Company's opening in New York.

"The expectant 33-year-old mom hit the red carpet in New York on Tuesday for her latest sighting since announcing she and husband Brandon Blackstock are expecting a baby boy-their second child after 1-year-old daughter River Rose Blackstock," E! News reported.

It continued, "The 'Heartbeat Song' singer looked radiant with soft waves in her blond locks and a bubblegum pink lip. If you've heard the age-old wives' tale about having more of a glow while pregnant with a boy, here's the proof."

A week ago, Kelly Clarkson announced on her own Instagram showing a photo of River Rose about the sex of her baby bump. She wrote, "In other news, River's gonna have a little baby brother :) #itsaboy We're so excited!"

"So exciting.... congrats kelly and to brandon, savannah, seth and especially river," one fan wrote.

Another said, "Awe , congratulations sweetie , so happy for all of you!!"

It would be no surprise that Kelly Clarkson would be blooming amid the baby bump announcement, since the "American Idol" alum said that motherhood changed her to the core.

"My whole life took a big 180," she told People. "I never thought I was going to be a mom, so it's very much changed my world in the most awesome way."

"I love what I do, but I feel like I relied on my career a lot for my self-worth. And now I'm more than that. I'm a mother and a wife and have this whole other thing going on."

Apart from River Rose and the new baby bump, Kelly Clarkson is also a mom to hubby Brandon Blackstock's kids, Savannah, 13, and Seth, 8.
