TMZ says they can confirm that Chely Wright is the celebrity coming out on the cover of People, and we've got more evidence, courtesy tipster BowlingForDollars: A Facebook photo of Wright that mentions her "profile in People mag Tuesday."
Here's a screencap of the Facebook page.
Seems like conclusive enough evidence, unless People is planning some kind of mass outing of B-list female country stars. The only question that remains is: What was BowlingForDollars doing on the Mitchell + Gold Facebook page? [Facebook; tip via BowlingForDollars]
Update: Confirmed! Chely Wright is People's May 5th gay cover story.
