Singer-songwriter Jewel is in Atlanta working on "Ring of Fire," a Lifetime movie about June Carter Cash. She has been updating her Twitter feed with details and photos. "Today I'm June 1970's style," she posted with this photo.

Here's Jewel frocked out as a 1950s era June Carter Cash with her first husband husband Carl Smith (Linds Edwards). This was a "Grand Ole Opry" scene.

June and Johnny! Jewel posted this photo of herself with Matt Ross, who will portray Johnny Cash in "Ring of Fire." "I gotta say, I love being a brunette," she wrote as a caption for this photo. The Lifetime movie is based on John Carter Cash's book about his mom and has filmed in a number of Atlanta locations including the Tabernacle downtown.
