Despite their recent separation, Kris Jenner was an eager attendee at her estranged husband Bruce Jenner's 64th birthday party on Sunday.

Photos from the big day were posted on social media by Kendall and Kylie Jenner, as well as their big sis Khloe Kardashian.

One of the shots shows Kris donning a mustache alongside other family members, while another displays Bruce's two elaborate birthday cakes.

Though they may be going their own ways, the family matriarch recently told "Extra," “I think what happens is when you spend so much [time] with somebody and you really love that person you can always remain really close. We have a family together and we raised a lot of fantastic children together."
