President Barack Obama is going to be among the final guests helping David Letterman wrap up the "Late Show" this month. 

President Obama is scheduled to be on the show Monday, May 4, which will be his third appearance since becoming president and eighth time overall, according to a CBS press release.

First Lady Michelle Obama is also a frequent visitor on the "Late Show." She made her last appearance on Thursday. 

Letterman is leaving his show for retirement, so when the First Lady was on the show he asked her what she plans to do with her time when she leaves the White House in a year and a half. 

Mrs. Obama joked, "You mean whether I'm going to be running for president or anything?" She later recommended taking the time to care for his 11-year-old son. 

Other notable guests coming on the show before Letterman's final show include actor Will Ferrell and musical guests the Avett Brothers and Brandi Carlile (Monday, May 4); actress Reese Witherspoon and musical guests Mumford and Sons (Tuesday, May 5); actor Martin Short and musical guest Norah Jones (Wednesday, May 6); actress Tina Fey (Thursday, May 7); and actor Ray Romano, standup comedian Brian Regan and musical guests Dave Matthews Band (Friday, May 8). 

The final "Late Show" is scheduled to air May 20.
