Escort is a polite way of saying "prostitute." From The Smoking Gun:

When approached by a reporter earlier this month in the lobby of a Las Vegas hotel, [Suzy] Favor Hamilton initially denied any connection with the escort service, Haley Heston’s Private Collection. But Favor Hamilton--who is married to her college sweetheart, a lawyer, and is the mother of a seven-year-old girl--eventually acknowledged her work as “Kelly.”

“I take full responsibility for my mistakes. I’m not the victim and I’m not going that route,” Favor Hamilton said. “I’m owning up to what I did. I would not blame anybody except myself.” She added, “Everybody in this world makes mistakes. I made a huge mistake. Huge.”

Favor Hamilton expressed concern that her story would be “sensationalized” by a reporter. It is hard, though, to imagine how that could occur. The actual events of the ex-Olympian's past year already seem like the fever dreams of a Lifetime producer who decided to adapt Luis Bunuel’s “Belle de Jour” for basic cable.

Yeah, I can't imagine how the story of a married former olympian working as a Vegas hooker--who apparently told everyone she slept with who she really was--would not be sensationalized.
