Jack White's pal is in a bit of a bad way...

Country legend LORETTA LYNN has been forced to postpone a June tour.

Lynn’s latest album, ‘Van Lear Rose’, was produced by White Stripes guitarist, and also features a duet between the pair – ‘Portland, Oregon’.

The singer’s dates scheduled for this month have been pulled, due to a back injury.

A statement reads: “Due to a back ailment, Loretta Lynn’s physician has ordered her off the road. All of her June concert dates have been postponed. More information to come regarding rescheduling.”
