First lady Michelle Obama will appear on ABC show "Extreme Makeover: Home Edition" as part of her initiative to support military families, the network said on Tuesday.

Michelle Obama's appearance on the show will be shot on Thursday in Fayetteville, North Carolina, and the episode will air in October, said Patrick Preblick, a spokesman for ABC.

The first lady is making the appearance as part of her Joining Forces initiative for military families.

The episode will focus on 15-year U.S. Navy veteran Barbara Marshall and her family. Michelle Obama and the "Extreme Makeover" team will help Marshall's mission of assisting homeless veterans by building a new house that will house several families, ABC said in a statement.

Michelle Obama last month filmed an appearance on the children's TV show "iCarly" which was also tied to her Joining Forces initiative. In 2009, she was seen in an episode of "Sesame Street" to promote healthy eating.

The reality TV series "Extreme Makeover: Home Edition" performs speedy and drastic home renovations for families that have suffered misfortune.
