Sheryl Crow Has a 'Theory' That Cell Phone Use Caused Her Brain Tumor

Katie Couric's new daytime talkshow is barely 24 hours old and it's already the source of controversy.

On yesterday's inaugural episode of Katie, guest Sheryl Crow volunteered a theory that her benign brain tumor was the result of cell phone use.

"There are no doctors that will confirm that," the 50-year-old singer told Couric, "[but] I do have the theory that it's possible that it's related to that."

As The Blemish put it, "oh, good, another celebrity with a theory."

Indeed: Crow said her meningioma was located in the "cell phone area" — a clinical term, no doubt — and placed the blame on excessive cell phone use early on in her career: "[In the] early, early days when I was promoting my first record, I did hours of phoners on the old archaic cell phones."

Of course, there is no existing data to back any of this up. Then again, there have been no long-term studies on the effects of cell phones on verbal diarrhea.

Someone should definitely get on that.
