Congrats to Kelly Clarkson! The 31-year-old pop star and first "American Idol" winner has married fiance Brandon Blackstock after dating for about two years.

The two tied the knot in Tennessee at Blackberry Farms, a 4,200-acre luxury hotel and resort in the Great Smoky Mountains on Sunday, Oct. 20, Clarkson said on her Twitter page on Monday.

"I'm officially Mrs. Blackstock :) We got married yesterday at Blackberry Farms in TN, the most beautiful place ever!" Clarkson tweeted, alongside a photo of the two standing on a grassy hill in their wedding attire.

She also shared a second picture on Twitter on Monday, showing the two kissing. (See both below) Clarkson wore a Temperley London vintage, lace wedding gown with bell sleeves and a v-neckline and a beaded headband. She carried a bouquet made up of what appeared to be sunflowers and lavender.

Blackstock is a Nashville-based talent manager. He and Clarkson began dating in 2011 after meeting through Blackstock's father Narvel Blackstock, who is Clarkson's manager and the husband of country star Reba McEntire.
