According to People, Obama will appear as part of her and Dr. Jill Biden's Joining Forces initiative that works to aid veterans and their families.
Obama will travel to Fayetteville, N.C., on Thursday to help the 'Extreme Makeover' team expand a community resource center for homeless female veterans.
Look for Obama to help build a greenhouse and children's play area when the episode airs in October.
Besides 'Extreme Makeover' and talk shows, Obama has appeared on 'Iron Chef America' to promote her healthy eating agenda, and recently booked a role on Nickelodeon's scripted series 'iCarly.'
On 'iCarly,' Obama will also be promoting the Joining Forces initiative, with Carly (Miranda Cosgrove) and her friends breaking rules and setting up a web chat so Carly can speak with her father, who is serving overseas, on his birthday.
Obama gets wind of the rule-breaking and meets Carly and her friends to have a chat "in the most positive way possible." The episode will likely air in January.
