Brandon Blackstock’s Children

Savannah Blackstock

Brandon Blackstock’s oldest child was daughter Savannah Blackstock. When Brandon Blackstock and Clarkson were married, Savannah Blackstock joined them for some red carpet appearances. She attended the 2017 American Music Awards with Clarkson and half-sister River Rose, posing for pictures as a trio on the red carpet. Savannah Blackstock sported a Chanel bag that read “Please Do Not Disturb.”

The following year, she snapped photos with her dad and Clarkson at the 2018 Billboard Music Awards. She matched the pair’s all-black looks in a black gown featuring a beaded silver collar.

It appears her final Hollywood event with her dad and Clarkson was in 2019. Savannah Blackstock smiled beside Clarkson, Brandon Blackstock, younger brother Seth Blackstock and half-siblings River Rose and Remy Alexander at a premiere for the animated flick “UglyDolls.” Clarkson voiced a character in the film. Blake Shelton, who Brandon Blackstock previously managed, also had a role in the movie.

Seth Blackstock

As mentioned, Brandon Blackstock and Ashworth’s youngest child, Seth Blackstock, joined the blended family for the “UglyDolls” Los Angeles premiere in 2019. But Seth Blackstock rarely made public appearances while his dad and the “Breakaway” singer were together.

In April 2020, he popped up in a video birthday message for Clarkson that was posted on the official X account for “The Kelly Clarkson Show.” “Happy birthday, Kelly. I love you,” Seth Blackstock sweetly said in the video, which was filmed in Montana.

Clarkson re-tweeted the post and wrote, “Just now seeing this and I am bawling! They’re all so cute! I’ve had a bit of a rough week and this just turned it around.”

River Rose Blackstock

Clarkson and Brandon Blackstock welcomed their first child together, daughter River Rose Blackstock, on June 12, 2014. The singer celebrated River Rose’s arrival by tweeting, “Our baby girl River Rose Blackstock arrived on June 12th! Thank you everyone for all of your well wishes! Brandon and I are on cloud 9!!”

In July 2025, Clarkson brought River Rose on stage during one of her “Studio Sessions” residency shows at the Colosseum at Caesars Palace. The duo, who both wore flared jeans and T-shirts, sang Clarkson’s “Heartbeat Song” together.

Fans shared videos on social media that showed River Rose giving her mom a hug before the duet began.

When the song ended, they embraced again and River Rose struck a pose to celebrate the performance. She previously sang the song with her mom in 2023 during Clarkson’s first Las Vegas residency.

Remington ‘Remy’ Alexander Blackstock

Clarkson shared on X that her son, Remington “Remy” Alexander Blackstock, was born April 12, 2016.

“Our little baby boy has arrived!!” she tweeted, adding “he is healthy & we couldn’t be happier or more in love!”

She also uploaded an adorable picture to Instagram of Brandon Blackstock holding their newborn.

Like his older sister, Remy also has musical talents. In November 2024, he crooned along to Frank Sinatra’s hit “My Way” on “The Kelly Clarkson Show.” The video went viral, racking up millions of views.

Remy returned to the talk show in January after becoming an internet sensation.

“Yeah, how much views did I get again?” he asked his mom before she and River Rose started laughing.

Clarkson recalled his reaction when she first told him the video had taken off.

“I said, ‘Man, buddy, you’ve got like over a million views, I think, on your (video),’ and he goes, ‘Do you get that many views?’” she playfully said.

She continued, “I was like, ‘Calm down … and not often.’”
