Kris Jenner -- Tells Bruce ... I Never Saw This Coming (VIDEO)

Kris Jenner broke down as she confronted Bruce Jenner during their "talk" ... essentially saying their relationship was a lie.

With smeared mascara, Kris seemed genuinely hurt during Monday night's "About Bruce: Part 2" special ... that she was the last person to whom Bruce told "the truth."

Bruce explained it was easier telling his secret to their kids than Kris. She does not receive that message well.
