Pop star Kelly Clarkson is now officially married to talent manager Brandon Blackstock, E! News reports, the two having wed at Blackberry Farm in Walland, Tenn., on Sunday, Oct. 20. in a romantic country wedding.

Built in the '70s, Blackberry Farm sits on 4,200 lush green acres, the perfect backdrop for the pop princesses to say "I do."

After struggling to decide between three dresses, the 31-year-old Grammy award-winning singer settled on a Temperley Bridal's "Jessamine" dress from the Iris collection. She completed the look with a white Maria Elena Headpieces headband and carried a bouquet of sunflowers and Bluebonnets, the official flowers of her home state of Texas.

For her engagement photoshoot, in contrast, Clarkson wore Marchesa and Monique Lhuillier, a crystal headband and bare feet.

Blackstock's two children from a previous relationship, 11-year-old Savannah and seven-year-old Seth, were among those in attendance for the ceremony. The couple had previously turned down the idea of having a big wedding in favor of a more intimate affair, just four months after the release of Clarkson's nupitals-themed country single, "Tie It Up."

"We're just gonna go off with the kids and go get married," Clarkson previously said. "It's just gonna be literally, seriously small." It was so small, in fact, that Blackstock's step-mother, country legend Reba McEntire, was out of town for a concert.

The newlyweds first met back in 2006 during rehearsals for the American Country Music Awards but didn't start dating until 2012, the year that Blackstock proposed to Clarkson with a custom engagement ring featuring a yellow canary diamond surrounded by white diamonds.

"I'm officially Mrs. Blackstock :)," Clarkson recently tweeted. "We got married yesterday at Blackberry Farms in TN, the most beautiful place ever!"

Earlier this month, Clarkson revealed that she is eager to become a mom, although she is now a step-mother to Blackstock's two children.

"Well, I'm totally gonna have a girl. My first child will be a girl - I know it in my soul," the star said on"Elvis Duran and the Morning Show," admitting that she already has her baby names picked out.
