Former first daughter Chelsea Clinton, 29, got engaged to her longtime boyfriend, banker Marc Mezvinsky, 31, over the Thanksgiving holiday. The daughter of Secretary of State Hillary Rodham Clinton and the former president met Mezvinsky while they were both students at Stanford. "We wanted to share that we are engaged!" the couple wrote in an email to friends. "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. Happy Holidays! Chelsea & Marc." (Photo: WENN)
