Former first daughter Chelsea Clinton is traveling by crutches and wearing a medical boot following an injury to her heel, a source told ABC News.
"She broke her heel," the source for Chelsea Clinton said. "She will be on crutches for the next couple of months."
Though one of the first pictures of Clinton on the crutches surfaced today, New Yorkers reported her using them as early as April 3 on social networking sites like Facebook and Twitter.
The source did not know how the injury happened. The offices for both of Chelsea's parents, Bill and Secretary of State Hillary Clinton, did not immediately return requests for comment.
With her marriage to longtime boyfriend Marc Mezvinsky slated for later this summer, Clinton is expected to recover in time to walk the aisle without the less-than-elegant boot and crutches.
Clinton, 30, and Mezvinky, 32, son of former Rep. Ed Mezvinsky and former Rep. Marjorie Margolies, were childhood friends in Washington D.C., and became close friends at Stanford University, which they both attended.
The couple announced their engagement on Friday, Nov. 27, 2009, saying: "We're sorry for the mass e-mail but we wanted to wish everyone a belated Happy Thanksgiving! We also wanted to share that we are engaged! 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."
Clinton has kept a notoriously low profile since her father's time in office, despite reportedly being a regular on the social circuit.
"I don't think Chelsea is one of those people that she has ever wanted to be the center of attention," said Hollywood film director Harry Thomason, who is a close friend to the Clintons, when the engagement was announced. "We can all see that over the following years, she had plenty of chances to be the center of attention in the White House and in her college years, and she's just always chosen not to. I think that speaks well of the people who raised her."
In 2008, she broke her code of silence and hit the campaign trail with her mother, speaking at events and college campuses all over the country.
Although Hillary Clinton failed in her bid for the presidency, supporters came away impressed with Chelsea, asking her again and again if she would ever consider a career in politics. As of last fall, she has insisted that she would not.
The future groom works with 3G Capital Management and Clinton is attending graduate school at Columbia University's School of Public Health.
