America's First Lady Michelle Obama is fast becoming a full-time Tv star - she has landed cameo roles on hit U.S. shows Nashville and Jessie.

President Barack Obama's wife will play herself in a Nashville episode based at a charity concert at the Fort Campbell army base in Kentucky. The episode is due to air in the U.S. on 7 May (14).

Meanwhile, she will also join the cast of the Disney Channel's Jessie for another appearance as part of her Joining Forces initiative, which provides support for military families.

Jessie star Debby Ryan says, "It's gonna be incredible, it's one of my favourite episodes."

The guest spots come after similar appearances on shows such as Sesame Street and iCarly, while Obama has also filmed a cameo on comedy Parks & Recreation, which is due to air in America on 24 April (14).
