After weeks of rumours and speculation, the 31-year-old singer revealed she finally tied the knot with fiancé Brandon over the weekend.
For the romantic, understated ceremony at Blackberry Farm -- a luxury resort in the Smoky Mountains in Tennessee -- Kelly chose a Temperely London lace gown, which she paired with a crystal headpiece and an unfussy updo.

"I'm officially Mrs. Blackstock :)" the Grammy-winner wrote via her Twitter account, sharing several snaps with her fans.
In one particularly gorgeous shot she is seen holding a rustic bouquet of sunflowers with purple daisies as her happy husband plants a kiss on her cheek.
The newlyweds, who had begun dating in 2012, had originally planned on having a big October wedding, with Kelly even posting engagement photos to her Twitter page. They scrapped that idea in favour of a low-key affair with just close family and friends.
Congratulations to the happy couple!
