Suzy Favor Hamilton, a three-time U.S. Olympian, has revealed that she has spent much of the past year working as a $600-an-hour escort. It's a stunning admission, and a decision that Hamilton now calls a "huge mistake," according to The Smoking Gun.

Since last December, Hamilton has, according to TSG, worked with Haley Heston's Private Collection in Las Vegas, and has gone on engagements in Las Vegas, Los Angeles, Chicago and Houston. The 44-year-old married mother of one worked under the name "Kelly Lundy," but apparently revealed her true identity to several male clients.

Hamilton responded to Thursday's story with a lengthy response and apology on Twitter:

    I realize I have made highly irrational choices and I take full responsibility for them. I am not a victim here and knew what I was doing. I was drawn to escorting in large part because it provided many coping mechanisms for me when I was going through a very challenging time with my marriage and my life. It provided an escape from a life that I was struggling in. It was a double life.

    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. As crazy as I know it seems, I never thought I would be exposed, therefore never hurting anybody. I have been seeking the help of a psychologist for the past few weeks and will continue to do so after I have put things together. I cannot emphasize enough how sorry I am to anyone I have hurt as a result of my actions and greatly appreciate the support from family and those closest to me. I fully intend to make amends and get back to being a good mother, wife, daughter, and friend.
