Rimes is organising an event in Jacksonville, Florida, and she will take to the stage to perform, while her husband hosts the concert.
She tweeted yesterday: 'I'm doing a benefit acoustic show in Jacksonville, FL on June 5 benefiting the tornado victims of AL. and MO. Details to come and Mr. Cibrian will be hosting :) lots of fun auction items too!'
