Bristol Palin has called off her wedding, less than one week out from the big day. The 24-year-old mother-of-one will no longer marry former US Marine Dakota Meyer on May 23. Bristol's mother, US politician Sarah Palin, announced the news on her Facebook account. "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," she wrote. "They have informed loved ones that unfortunately the announced celebration planned for May 23 will not be held." Sarah said that, although the wedding was off, the two families still planned to get together on the day. "Family members and close friends know they are welcome to share a great bar-b-que on the farm that day," she wrote. Sarah posted the statement with an image of a beach with the words: "Trust in God's timing. It's better to wait a while and have things fall into place than to rush and having things fall apart." The news comes following rumours that Meyer, who won a Medal of Honor – America's highest military honour – for his service in Afghanistan in 2011, had a secret wife and family. Online tabloid RadarOnline started the story, publishing a copy of a marriage certificate, which appeared to show Meyer, 26, married to Michigan woman Cassandra Wain in 2008. However, in a statement delivered through her mother's Facebook account, Bristol denied the rumours, saying she knew about Meyer's previous wife and that the couple had legally divorced. "Regarding salacious headlines in recent days about 'secret wives', Dakota and I discussed our past relationships prior to our engagement," she said. "Dakota was legally divorced years ago, as any good reporter could and should have disclosed to readers." Bristol Palin first entered the spotlight aged 17, when her teenage pregnancy coincided with her conservative mother's nomination for Vice President in the 2008 US presidential election. She gave birth to son Tripp in December 2008, three months after her 18th birthday. Bristol and Tripp's father Levi Johnston ended their engagement in March 2009. Since then, she has enjoyed a career as a reality television contestant, appearing on Dancing With the Stars in 2010, as well as on her own show, Bristol Palin: Life's a Tripp.
