Scott Disick's parents will always have a special place in his heart.

Kanye West’s lavish proposal to Kim Kardashian was finally revealed on the Feb. 16 episode of ‘KUWTK.’ But the episode ended on a bittersweet note as Scott and the Kardashians paid tribute to his beloved mother, Bonnie Disick, who passed away on Oct. 28.

Scott Disick was heartbroken when his mother, Bonnie Disick, died at the age of 63 after a long illness. On the Feb. 16 episode of Keeping Up with the Kardashians, we got a look at an emotional Scott, who was by his mother’s side at the hospital in New York in the days leading up to her death. In the show’s final moments, Scott remembered his mom in a touching tribute, and asked viewers for their support in coping with his devastating loss.

Even though tonight’s episode centered around Kim Kardashian‘s fairytale proposal from Kanye West, there was a strong undercurrent of sadness running through the episode as Scott, Kourtney Kardashian and the rest of their families realized they would soon have to say goodbye to Scott’s mom.

After spending several heartbreaking days with his parents in New York and missing Kimye’s engagement celebration, Scott surprised Kourtney by flying back to LA to take in a Kanye concert with the whole Kardashian clan. Even though Scott said he was doing fine, he appeared visibly distraught during the show.

The final moments of this week’s episode of KUWTK revealed that Bonnie passed shortly after the concert. ”Bonnie Disick died the day after Kanye West’s concert in Las Vegas. Scott and Kourtney were by her side,” a tribute to Bonnie read. So heartbreaking!
