Doherty “always stuck up for me,” Spelling continued.

“Always believed in me when I didnt or couldnt believe in myself.”

She empowered sexiness, strength, empathy, and all topped off with wicked humor.”

“Ill carry the torch on,” Spelling promised.

“And Ill stay rebellious for you.

Love you with all my heart.”
