Meet Natalia McLennan, a former escort who says she actually trained Eliot Spitzer's call girl, Ashley Dupre. She was one of the most expensive call girls in the world, and you won't believe what her going rate was!

"I was the ultimate New York escort," Natalia tells ET. "Clients [paid] $2,000 an hour for me. It was great -- and I had a two hour minimum."

As for her take on Ashley and Spitzer, she says, "I don't understand why he made the choices that he made. He's a public figure and he's married with three teenage daughters. I think it's just really unfortunate."

Like Ashley, the 28-year-old Natalia had hopes of fame. So how did the aspiring actress turn into a high priced hooker? Unbelievably, her own boyfriend owned a brothel -- and turned her into a call girl. Soon, she was the headliner of an escort service that was run out of a loft in downtown Manhattan, and the client list actually included celebrities!
