If there's one celebrity name that pops into my head when I hear the words "stick thin," it's Mary-Kate Olsen. Kate Moss is up there too, but I'm guessing Mary-Kate may be known more for her skinniness than her Full House stardom. Hey, things might be changing, though.

Tabloids are reporting that the normally waif-like Olsen twin has put on a few pounds. This all stems from rumors that Mary-Kate is pregnant. Her rep says she absolutely is not. Apparently, the 22-year-old reveals in her new coffee table book Influence that doesn't even want kids. Maybe after previously battling anorexia, she just wants a few extra pounds. Not a bad idea, I'd say.
