Los Angeles - Kim Kardashian West has revealed her mother Kris Jenner has been questioning if her "memories were real" with Bruce Jenner since he announced he was undergoing gender reassignment.
The 34-year-old star has admitted Bruce's decision to become a woman has been tough on her mother and left her confused about whether the couple were living a lie throughout their 24-year marriage - which produced two daughters, Kendall and Kylie Jenner.
Kim took to her Twitter account to tweet as she watched the first Keeping Up with the Kardashians: About Bruce episode about his sex change on Sunday night.
Breaks my heart my mom questions if her memories were real. That was 4sure a part of Bruce's life. Must be hard to go thru this as his wife
