Karlie Kloss is hosting a new TV show loaded with a slate of powerful celebrities ... but the one person Kloss wasn't able to land is the leader of the "Squad."
"Movie Night with Karlie Kloss" will feature the fashion model inviting "some of her closest friends for an evening of movies, games, baking, and fun" while watching classic movies like "Dirty Dancing," "Never Been Kissed," and "Harry Potter."
Sources close to production tell us Kloss tried to get her Swift to come on the show ... but Tay Tay "politely declined due to scheduling issues."
Kind of a bummer, considering Swift would have fit right in with her squad and obviously helped boost the ratings for her friends show.
The show is set to premiere December 28 on Freeform.
