Kelly Clarkson's Estranged Ex Brandon Blackstock Responds to Divorce – Inside Their Custody Agreement

Just over a month since Kelly Clarkson filed for divorce from Brandon Blackstock, he responded to the terms she set out, including her request to enforce their prenuptial agreement.

The 38-year-old singer filed for divorce in Los Angeles Court on June 4 - a move that surprised since nothing recently happened specifically to upset the marriage cart.

The pair tied the knot in 2013, the exact date listed as October 20 in Clarkson's divorce petition. Sharing two kids, Remington Alexander is the youngest at four years old and River Rose just a year older.

While Clarkson marked the date of their separation as "To Be Determined," she did request joint legal and physical custody with her soon-to-be ex-husband, a point Blackstock agreed with, according to documents obtained by The Blast.

In addition, Clarkson, who shared her struggle with depression last month, requested that the court deny any spousal support and also asked for the enforcement of their signed prenuptial agreement.

Attorney Samantha Spector is reported to handle Blackstock's side of the divorce, and the former couple appears to be on the same page regarding the date of their separation and custody of their kids, but that's all.

With regards to spousal support, Blackstock chose the "other" option, which he reportedly listed as "reserved," so they will have to work through that before finalizing the end of their seven-year marriage.

According to sources close to the couple, their relationship had simply run its course, and there was no specific incident that prompted their split.

However, in the wake of her divorce filing, Clarkson is said to be focusing on the wellbeing of their children, as the source added:

"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."

But other factors reportedly also came into play, as the couple had marital problems for some time before Kelly Clarkson decided to make their split official.

In the meantime, Clarkson had returned from Montana, where she and her family quarantined to Los Angeles, and their time spent together in isolation exasperated their problems.
