"I Thought He Was Having An Affair" -- Kendall Jenner On Finding Bruce Jenner's Makeup Kit

In part one of Keeping Up With the Kardashians: About Bruce,  premiering tonight on E! at 9 p.m., an emotional Kendall Jenner recalls being a little kid and sensing that father Bruce Jenner had a secret.


"I just remember being little and not really knowing what was going on,"

"We would find things like makeup or lipstick, and we thought he was having an affair at one point," Kendall says, blinking back tears. "And we didn't know what to do, we didn't want our family to be broken up."

Bruce and Kris Jenner were married for 22 years before separating in 2013."
