I'm sure, like Cristina said its been photoshopped. Its relatively easy to do, especially with that background. People always want to exaggerate things. I'm sure she's super skinny, and maybe it isn't, but that's rediculous.
Her leg looks like my arm.
I just showed this picture to my husband and he is in shock,.... I guess she's not the love of his life anymore,.. why is she jogging anyway,.... hopefully she's running to the nearest McD's,... She should have been the girl in "supper-size-me"
