Caitlyn Jenner has been forced to cancel her upcoming speaking tour. Some sources said that the cancellation might be due to lack of interest and slow ticket sales, while others claimed that it was purely because of scheduling conflict.

The tour was to be called "Up Close and Personal", with the former Olympian set to give her significant speeches following her transition, along with her lecture organization Unique Lives and Experiences. She was supposed to travel to five cities including Toronto, Vancouver, Denver, San Francisco and Seattle, starting from February 22.

Tickets were on sale with prices ranging from $40 to $500, but an insider from the Toronto venue revealed that there were still "a lot" of tickets left when Jenner canceled the tour. Though so, the transgender's rep insisted that it's "possible" to reschedule the speaking gigs, adding that there was "simply a conflict in work dates."

Previously known as Bruce Jenner, the reality show star came out as transgender in April 2015 and made her debut as Caitlyn in a Vanity Fair cover story in June 2015. Before transitioning, Jenner had a good career as a motivational speaker. She used to be paid $5,000 to $10,000 for each speaking engagement. According to a 1979 report by The Toledo Blade, Jenner had an average of 40 speaking engagements a year.
