NEW YORK - Chelsea Clinton, daughter of former president Bill Clinton, is to marry her longtime boyfriend next summer.

Clinton, 29, revealed the plan in an email to friends sent Friday, the day after the Thanksgiving holiday.

"We wanted to wish everyone a belated Happy Thanksgiving! We also wanted to share that we are engaged!"

Clinton and investment banker Marc Mezvinsky were erroneously reported to have been about to tie the knot this summer in the upscale east coast resort of Martha's Vineyard.

Their email message said: "We didn't get married this past summer despite the stories to the contrary, but we are looking toward next summer and hope you all will be there to celebrate with us."

Clinton is the only child of Bill Clinton and Hillary Clinton, who was beaten by Barack Obama in last year's contest to become Democratic presidential candidate. Hillary Clinton now serves as Obama's secretary of state.
