Actress Nikki Reed and Natale Morales from "Today" were among the celebrity guest swimmers who joined Diana Nyad during a three-day swim for Hurricane Sandy.
The swim-athon was held to raise money for the victims of the super storm, which devastated the East Coast in October 2012.
The "Twilight" star, 25, tweeted after the event: "Such an inspiring day swimming with @diananyad." She added: "Guys please visit http://say.ly/Uki6Wef and donate anything you can, even a dollar!"
Nyad swam for 48 hours to keep awareness focused on the cause because some people are still displaced after enduring the massive storm.
