The 46-year-old actress took to Instagram to pay a heartbreaking tribute to her 85-year-old father Brian who passed away recently.

"How do you live without someone that you can’t live without?" she began the note alongside a picture of her father.

"How lucky am I to have had you as my dad. You were hilarious, positive and my best friend,” Fisher added.
