Disney canceled an appearance by a three-time Olympian at an upcoming Disneyland event after she revealed that she has been living a double life as a prostitute.

Suzy Favor Hamilton, 44, a competitive runner who won seven U.S. titles, admitted Thursday that she was a prostitute after the Smoking Gun website posted a story revealing she has been working for a Las Vegas escort service. See full story about Suzy Favor Hamilton.

A day earlier, Disney issued a news release stating that Favor Hamilton was scheduled to speak at an August 2013 expo during the Disneyland Half Marathon weekend. On Thursday, the news release on Disney’s website no longer included Favor Hamilton’s appearance.

Bob Hitchcock, a spokesman for runDisney, which runs the company’s races, said Favor Hamilton is no longer scheduled for future Disney events.

Favor Hamilton previously spoke at and led a dance at an August meet-up at Disneyland Half Marathon events in Anaheim. In February, Favor Hamilton appeared at a Princess Half Marathon event at Florida’s Walt Disney World.

The Smoking Gun website implied that Favor Hamilton continued to work as a prostitute, using the name “Kelly Lundy,” during her trip to Anaheim. The escort service where she worked posted on its Twitter account that “Kelly” would be available in Orange County during that weekend, the Smoking Gun said.

On her personal account, Favor Hamilton, who is married and has a child, tweeted about her Disneyland Half Marathon experience that weekend. “Had a fabulous time at the Disneyland Half-Marathon this weekend! Met so many fabulous people :),” states a tweet on @favorhamilton on Sept. 3.

On Thursday, her tweets took a more somber tone.

“I do not expect people to understand, but the reasons for doing this made sense to me at the time and were very much related to depression,” states @favorhamilton. “As crazy as I know it seems, I never thought I would be exposed, therefore never hurting anybody.”

The Associated Press and the Smoking Gun contributed to this report.
