First Lady Michelle Obama will make a special guest appearance as herself on the May 3 episode of NCIS -- and we've got your first look. The episode, titled "Homefront," involves a 14-year-old boy who witnesses a home invasion, and will highlight the real-life organization Joining Forces, a support organization for military families that Mrs. Obama co-founded with Dr. Jill Biden several years ago. The group provides services to the spouses and other loved ones of military personnel who are deployed overseas.

"At the end of the day, this was really about supporting Joining Forces," NCIS executive producer Gary Glasberg tells TVGuide.com. "It's something that we've been aware of and conscious of in our research and storytelling, and this was an opportunity to really focus on it, so that people can be aware of everything it's done. When we reached out to express our interest in the organization, the opportunity came up for the first lady to participate. Originally the idea was for her to come and spend some time with us, and then, to quote them, they invited us to come and film 'in their house.' And that turned out to be just a dream come true for us."

Obama filmed her cameo alongside Gibbs (Mark Harmon) and the teenage crime witness, whose father is a member of the military. "His father is overseas. His mother is struggling to sort of make things work here at home," Glasberg explains. "Joining Forces is there supporting the family, and towards the latter part of the episode, there's an opportunity for his mom to meet with and converse with the First Lady, and Gibbs is also there. So, it's a really lovely scene and she was fantastic."

The episode will also earn NCIS a place in the television history books. "We're the first dramatic film production to actually film in the White House," Glasberg says. "The West Wing, I believe, filmed outside. We got to film inside."

This isn't Mrs. Obama's first scripted television appearance; however, it is her first on a prime-time network drama. She has previously made cameos on iCarly, Jessie and Parks and Recreation.

"She was extremely well-versed in NCIS, and we were really honored and thrilled that that was the case," Glasberg notes. "To have her participate was unbelievably special for us, and she was fantastic."

NCIS airs Tuesdays at 8/7c on CBS.
