It's official! Kelly Clarkson tied the knot with Brandon Blackstock near their home in Tennessee on Sunday. Clarkson tweeted: “I’m officially Mrs. Blackstock,” Kelly tweeted on Monday, along with the photo above. “We got married yesterday at Blackberry Farms in TN, the most beautiful place ever!”

Blackstock is the son of Narvel Blackstock, Clarkson's manager, and stepson of country singer Reba McEntire, who became friends with Clarkson after they performed a duet on American Idol in 2002.

Congrats to the happy couple!
