Caitlyn Jenner's 5-city speaking tour has been cancelled.

Jenner was set to embark on her 5-city "Unique Lives and Experiences" tour February 22, but the tour - which was scheduled to come to Denver's Bellco Theatre on February 24 - has been canned due to scheduling conflicts.

TMZ spoke to the venue in Toronto that was going to kick off the tour; they say there were still "a lot" of tickets left for Jenner's speaking engagement when she cancelled.

Bruce's speeches were known to sell out regularly.
