She’s “All About That Bass” — and now she’s all about the Illinois State Fair.

Fair officials say that pop star Meghan Trainor — who was recently sidelined with vocal cord surgery — will be the big pop act signed for the State Fair’s grandstand this year, performing Saturday, August 13th, as part of her “The Untouchable Tour” being announced Wednesday.

Tickets for the Trainor show — which will include Academy Award-nominated actress and singer Hailee Steinfeld — will range from $28 to $50.

But, as with all the other grandstand acts announced, it’s not yet known when ticket sales will start.

The fair says they have two more dates yet to announce for grandstand acts — August 15th, and August 18th.
