(Now updated with comment from new O editor) Last month, we told you about chaos at Women's Health. Well, another high-ranking editor has left the Rodale publication: Executive editor Alison Gwinn is joining O, The Oprah Magazine in the same position. She'll start on March 2nd.

Gwinn, who previously worked at InStyle, Entertainment Weekly, and The New York Times, had been with WH since 2007.

Jumping to a new job is an interesting choice for the executive editor. Her former publication might be struggling to retain staffers, but O can't keep ad pages, losing 23 percent in the fourth quarter year-to-year. It makes you wonder how bad things must be at Women's Health.

UPDATE: Gwinn emailed FBNY the following: "I've loved working with Michele in the short time she's been here, and had this opportunity not presented itself, I would have happily stayed at Women's Health. But O is one of my favorite magazines and, frankly, it's a move that I couldn't pass up."
