Kelly Clarkson is no longer "Miss Independent" ... she's Mrs. Blackstock!

The original "Amerincan Idol" winner married talent manager Brandon Blackstock on Sunday at Blackberry Farms in Tennessee -- what Kelly calls "the most beautiful place ever."

Clarkson, 31, wore a gorgeous Temperly London wedding gown for her big day -- and she already shared some photos of her in her stunning lace dress.

With her hair done up and holding a bouquet of sunflowers, Kelly has a big smile on her face in the pic, as her new husband kisses her forehead.

This is the first marriage for Kelly. Brandon -- who is Reba McEntire's stepson -- has two kids (Savannah, 11, and Seth, 7) from his first marriage.

Congrats to the happy couple!

Kelly will forever be our favorite "American Idol" star -- check out the gallery below to see what the rest of the Season One contestants have been up to lately ... and what they look like now!
