Michelle Obama 'Terrified' About 'iCarly' Debut

Michelle Obama stormed Los Angeles on Monday to promote her Joining Forces initiative with the Hollywood community, as well as to shoot her cameo appearance on Nickelodeon's "iCarly," for which she admits she is "terrified."

"Let's say I'm the coolest mom on the face of the planet," said the first lady in reference to the Nickelodeon show. "We are big fans of 'iCarly.' This is an example of the way that we can integrate these [Joining Forces] storylines into shows, and it's important for kids to hear themselves in the shows that they love. But I'm going to put on my acting cape, I've been memorizing my lines – I am terrified. I can give a speech, I can talk to you all, but oh hoh hoh, I'm shaking."

At the Writers Guild of America, West Theater in Beverly Hills, the first lady addressed the movers and shakers of Hollywood to inform and inspire their memberships about the service of America's military families as well as shed light on the unique challenges military families face, showcasing the families' strength, resilience and service to our nation.

Stars in attendance alongside service men and women included 'Super 8' writer-director and program moderator J.J. Abrams, Chaz Bono and Blair Underwood.
