Deceived Kelly Clarkson was dealt a double-whammy when her ex-husband, Brandon Blackstock, passed away recently – not only was the songbird not mentioned in his obituary, but it publicly revealed his romantic relationship with her former assistant for the first time, RadarOnline.com can reveal.
Blackstock, 48, died on August 7 after a three-year battle with cancer. Clarkson, 43, who shared two children, River, 11, and Remy, 9, with the talent manager, filed for divorce in 2020. It was finalized in 2022.
Kelly's Pain After Ex's Death
Brandon Blackstock's obituary highlighted Brittney Marie Jones as his partner, omitting any mention of Kelly Clarkson.
His obituary omitted any reference to the talk-show host, but did praise Brittney Marie Jones, who used to work for Clarkson, calling her his "beautiful and loving partner in life and business."
Until his death, Blackstock and Jones had been living together at his home in Butte, Montana.
Their relationship was just "the icing on the cake of the disappointment" Clarkson felt over the dissolution of their marriage, an insider said.
"Brandon chose to move on with someone Kelly knew and trusted, and that just adds to the person he ended up being to her. He was a great father, but wasn't a great husband."
Not Placing Blame On Brandon's Girlfriend
Sources said Clarkson did not blame Jones for her relationship with Blackstock.
Despite the crushing betrayal of her ex moving on with someone she trusted, the source said Clarkson "doesn't blame" her former assistant.
The American Idol winner's number-one objective was protecting her children, and "Kelly knew that Brittney wasn't going to be a problem with her and her kids – there was never a misunderstanding between them," the source shared.
Clarkson also didn't hold it against Jones, despite the legal wranglings between her and Blackstock.

A California ruling in 2023 ordered Blackstock to repay Clarkson $2.6 million over unlawful commissions.
