Kelly Clarkson's ex-husband Brandon Blackstock's daughter Savannah, 20, is pregnant amid his divorce

KELLY Clarkson's ex-husband Brandon Blackstock's daughter Savannah is pregnant.

Taking to Instagram on Wednesday, Savannah, 20, announced that she is expecting her first child with her boyfriend Quentin Lee.

The exciting baby news comes as Kelly, 39, and music manager Brandon, 44 continue to battle it out in their nasty divorce and legal battle.

Savannah showed off her baby bump while posing in a field at sunset in a sweet maternity shoot.

She also hugged Quentin and danced with him in the cute photos, which she captioned: "The most precious secret we’ve ever kept…"

BABY ON THE WAY

Quentin added in his own announcement post: “Sorry … been busy. #newchapter.”

It's unclear how long the parents-to-be have been dating, but they went Instagram official in November 2019 during a Florida beach trip.

Last year, Savannah shared a heartfelt tribute to Quentin for his birthday, writing: "I am so blessed to have found someone so perfect for me.

"I look forward to being apart [sic] of your growth, and I will always be right by your side through thick and thin.

"You give me happiness I never knew existed. You have my heart forever and always.

Savannah is Brandon's child from his marriage to first wife Melissa Ashworth. They also share son Seth, 14.

Brandon met Kelly after his 2012 divorce from Melissa.

He married The Voice judge in 2013 and they have two children together - daughter River, seven, and son Remington, five.

Kelly filed for divorce in June 2020, citing "irreconcilable differences" and was later granted primary custody..

She is having to dish out $150,000 per month in spousal support, along with around $45,000 a month for child support.

But Brandon will be the one paying for the upkeep of their sprawling Montana ranch, which costs around $81,000 a month to run.

She has something to celebrate, however, as a judge has fully upheld the singer's prenuptial agreement that Brandon had been fighting.

"2020 has been a dumpster fire," the 39-year-old told the audience on her talk show.

"2020 has brought a lot of change also to my personal life. Definitely didn't see anything coming that came.
