The politician took to Facebook.com to announce her daughter's sad news that her nuptials on Saturday (23May15) will not go ahead.
She writes on the social network site, "Bristol and Dakota couldn't be more thankful for the love and support of family and friends over the past months while preparing for their wedding. They have informed loved ones that unfortunately the announced celebration planned for May 23 will not be held.
"Many friends and family still look forward to getting together that day in Kentucky anyway - and the Palins and Meyers are happily looking forward to still being at 'the old Kentucky home' on May 23 to celebrate life, in general!... All involved, especially Dakota, Bristol and Tripp, and their parents and grandparents, thank supporters for the love they've expressed."
Bristol, who appeared on U.S. reality show Dancing with the Stars in 2011, was previously engaged to her six-year-old son Tripp's father, Levi Johnston, but called off the engagement in 2009. She met Meyer last year (14).
