The couple has been dating since February 2012. They exchanged vows Oct 19, reports femalefirst.co.uk.
Renee Beranek, a relative of an employee at the venue, gave out the news.
"Kelly Clarkson got married at Blackberry Farm today...My sister is the chef at Blackberry Farms... Crazy! (sic)," Beranek posted on microblogging website Twitter.
The 31-year-old had sparked speculation of her nuptials after she filed for a marriage license in the town of Sumner County, Tennessee, Oct 15. It gave the couple just 30 days to get hitched.
