It seems impossible for First Lady Michelle Obama to top her recent Carpool Karaoke performance, but she's going to have the chance to try.

CBS announced Wednesday that the first lady and education enthusiast is scheduled to appear on "The Late Show with Stephen Colbert" on Tuesday, Sept. 20. Obama will be returning nearly a year after her first appearance on the show, back on Sept. 28, 2015. This time around, the first lady will be there to promote "Let Girls Learn," an initiative she launched with the president in March 2015 that aims to help girls around the world go to school. They've been working on it with the Department of State, USAID, the Peace Corps, and the Millennium Challenge Corporation, among other agencies and programs.

While she'll obviously be there for a serious purpose, Obama has shown off her sense of humor in the past and we expect it to come out with Colbert. We'll miss her rapping along with Missy Elliott like she did with James Corden, but her "Late Show" visit is bound to be interesting nonetheless.

"The Late Show with Stephen Colbert" airs on weeknights at 11:35 p.m. ET on CBS.
