The First Lady is going country – Michelle Obama will make a cameo on TV's Nashville!

Obama, 50, will star as herself on the show May 7, ABC announced. Kellie Pickler is also set to appear in the episode, which finds country music queen Rayna James (Connie Britton) organizing a charity concert at Army base Fort Campbell in Kentucky.

The guest spot marks the latest stop on Obama's TV tour: She's visited the sets of Sesame Street, iCarly, and The Biggest Loser to promote physical fitness and healthful eating for her Let's Move! initiative.

Next up, she'll appear on Thursday's season finale of Parks and Recreation.
