The pretty blonde recently made a pact never to bare all or pose topless again - and the Tennessee band was the first to realise she's deadly serious about her decision after they booked her to appear in their new promo.

Wilkinson agreed to roll around in the mud in the racy new video, which she shot in Nashville over the weekend (16-17Jun12) - but she refused to strip off.

She tells news show Access Hollywood Live, ""They wanted me to reveal myself and I said, 'No, I'm OK... I'm kinda done with that!'""
