David Letterman's return to the talk show world has been shrouded in mystery, but this video reveals a huge puzzle piece -- youngest ever Nobel Prize winner, Malala Yousafzai.
Malala was spotted leaving a taping of Dave's Netflix show in NYC Monday night. She says it went great, and best we can tell -- she's guest #2 of 6.
Rumor is Barack Obama was Dave's first guest a month ago. Dave's not confirming that, or much at all, about his new gig. It's unclear who the next 4 guests will be, but we did see 2 other famous possibilities.
John Krasinski and Emily Blunt were spotted leaving the studio, but they could've just been guests in the audience. Again, Letterman ain't saying much.
Malala's gotta be great though. Pretty sure it's Dave's first time sitting down with the youngest Nobel Peace Prize winner, who fought for girls' rights to education, and survived the Taliban.
