"In honor of Valentine's Day I wanted to share some news. I met the love of my life. And we got hitched! My heart is full. Thank you Brendan McLoughlin for loving me for.... me," Lambert wrote.
People magazine reports that the wedding was held a while ago.
According to People, McLoughlin is a NYPD officer from Staten Island. Lambert hasn't shared information about how their relationship began.
Lambert was previously married to country star Blake Shelton. The pair divorced in 2015. Following her split from Shelton, Lambert dated Americana singer Anderson East. Lambert and East broke up in 2018, after which Lambert reportedly began dating Evan Felker, the lead singer of Turnpike Troubadours. In August of 2018, Lambert told The Tennessean she was "single and happy."
"Love is a hard road sometimes and it's been a roller-coaster ride for me, but I'm definitely thankful for all the ups and downs because I've had some really good songs come out of it," Lambert told The Tennessean last year. "You've got to take the bad parts and put them on paper and then move on to the happy parts."
