First Lady Michelle Obama, no stranger to the late-night talk show circuit, is paying a visit to Stephen Colbert. She’ll appear on CBS’ The Late Show on Monday, September 28. In fact, some have suggested over the years she’s overexposed, TV-wise.

Last time she visited Colbert, when he was on Comedy Central, the late-night host asked her, “As someone who has appeared on both my show and also appeared on iCarly, which of us do you think has more gravitas as a broadcaster?”

“Very deep — I should add some random dancing to my show,” Colbert rebutted.

Typically, Obama comes on a TV show to plug something but, then again, who doesn’t? That time she visited The Colbert Report, in 2012, for instance, she was celebrating the first anniversary of the Joining Forces government program to support service members, veterans, and their families. Visiting Colbert on CBS for the first time, she’ll highlight her “Let Girls Learn,” initiative that seeks to help the more than 62 million girls around the world, half of whom are adolescent, attend school and complete their educations, according to CBS. She’ll also plug her “Reach Higher” initiative, an effort to inspire every student in America to complete their higher education

“It’s always an honor to have the First Lady,” Colbert said in this morning’s news. “Better than that, it’s always fun!”
