Mary Kate Olsen's rep says she's resting comfortably after having been hospitalized with a kidney infection on Monday. Ironically, this comes not long after Olsen recently stated that she's in perfect health.

"Mentally, physically, I feel pretty on top of my game right now," she told EW.com in September, as she prepared for her debut in Showtime's Weeds. "Talk to me next week, I don't know. Today, I feel good."

Personally, when I think Mary Kate Olsen, I think a picture of health. Because nothing puts a girl on top of her game like a steady diet of Marlboros and Ex-Lax. The sugar-free Ex-Lax, of course -- just because a girl likes to be healthy doesn't mean she can't watch her waistline, right?
