The 'Breakaway' hitmaker filed for divorce from the 43-year-old music manager in June, after seven years of marriage.

And now, according to court documents obtained by The Blast, Brandon has agreed to the 38-year-old singer's request to share custody of River Rose, six, and Remington Alexander, four.

Kelly also asked for spousal support and for the former couple's prenuptial agreement to be implemented.

And in response, Brandon - who also has Seth, 13, and Savannah, 18, from a previous marriage - marked the box "other" and "reserved", which suggests that this is something he's willing to discuss.

The news outlet also reports that there was no reason for their split, simply that their relationship "ran its course".

Both Kelly and Brandon also left the date of their separation as "To Be Determined".

The 'Since U Been Gone' hitmaker had cited "irreconcilable differences" as the legal grounds for the divorce in her filing and also asked to legally change her name back from Kelly Blackstock to Kelly Clarkson.

The pair first started dating in 2011 and tied the knot in 2013.

The latest developments in their divorce come after it was claimed Kelly is focusing her energy on their two children in the wake of the split.

An insider said: "She had to work through a lot of hurt from her childhood. Her priority is making sure her children grow up in a stable, loving environment."

The singer is also keen to remain close with Brandon's children Savannah and Seth.

The source added: "She's always thought of Seth and Savannah as her own too, and she has a special relationship with both of them. Kelly wants to remain close with her step-kids."

Meanwhile, it was recently claimed the coronavirus pandemic and its subsequent lockdown had "exacerbated" many issues for the former couple.

One source explained: "It was a stressful time. Quarantining exacerbated any issues. Things had changed in their marriage and the split was a while coming. They both work so hard. It's nearly impossible to enjoy each other, especially with the children needing constant attention.

"Kelly's been through a lot, and she thought Brandon was her happily ever after. It's very sad."

Kelly and Brandon had been quarantining together in Montana with their kids, and the 'Piece by Piece' singer previously admitted it was an "emotional rollercoaster".

In an interview conducted before she split from Brandon, she said: "Honestly, I have been on an emotional roller coaster. This has been really hard as a working parent, because I'm still doing all the same jobs.

"It's been exhausting honestly, cooking every meal and cleaning nonstop after toddlers and teenagers! Everybody's learning from home now and the teaching! So, everything has been crazy."
