Kate Beckinsale's mother, Judy Loe, passed away on Tuesday (July 15) after a battle with stage 4 cancer.

The Serendipity actress posted a tribute to the late 78-year-old on Instagram, revealing she didn’t want to post it but felt she had to since she was registering her mother’s death certificate, which would soon become public record.

"She died the night of July 15th in my arms after immeasurable suffering. I have not picked all the best photos, nor the best videos, because I cannot bear to go through my camera roll yet. I deeply apologise to any of her friends who are finding out this way or through the press, but I cannot go through her phone. I am paralysed."

Beckinsale explained that her mother was not only her "dearest friend" but the "love of my life" and had the biggest heart.

"Jude was the compass of my life, the love of my life, my dearest friend. The vastness and huge heart of this tiny woman has touched so many people who love her dearly. She has been brave in so many ways, forgiving sometimes too much, believing in the ultimate good in people and the world is so dim without her that it is nearly impossible to bear."

The Canary Black star wrapped up the post by mentioning that this was her biggest fear because of how deeply she loved her mother. The emotional caption was accompanied by a carousel of photos encompassing Judy's final moments and greatest adventures.
