Another first for multi-hyphenate Michelle Obama: the First Lady will join the cast of NCIS, albeit only for one episode.

On April 21, CBS released the first photo of the First Lady guest starring on the drama, which shows her in the White House's famed blue room, conversing with Agent Gibbs. The episode will also be a first for the rest of the NCIS cast, as they had the opportunity to film inside the White House. It will air on May 3.

The First Lady's appearance is part of a campaign for which Obama has teamed up with Dr. Jill Biden, called "Joining Forces." The initiative aims to raise awareness of the challenges faced by, and provide greater support to, military veterans and families.
