"Devastated at this monumental loss," Ridley said in a statement to ET. "How lucky we all are to have known her, and how awful that we have to say goodbye."

Fisher died on Tuesday after going into cardiac arrest on a flight from London to Los Angeles last week, but shared a close bond with Ridley before she died.

In fact, the two shared a chat last year for Interview magazine, where Fisher offered advice to Ridley, from one Star Wars heroine to another.

"Listen! I am not a sex symbol, so that's an opinion of someone… I don't share that," she told Ridley at the time. "You should fight for your outfit. Don't be a slave like I was."

While Fisher wasn't the biggest fan of her memorable Return of the Jedi costume, she didn't exactly mind her "space kiss" with Harrison Ford. "I'm looking forward to your space kiss," she told Ridley. "You're going to have one. Every girl does."

"We'll wait and see," Ridley replied.

Fisher and Ridley will share the screen once more, when Star Wars: Episode VIII is released on Dec. 15 next year.

Ridley isn't the only member of Fisher's Star Wars family to mourn the actress. Mark Hamill, Anthony Daniels, Peter Mayhew, Billy Dee Williams, Warwick Davis, and Dave Prowse all took to social media to pay tribute to Fisher, while Harrison Ford released a heartbreaking statement on the actress' death to ET. 

"Carrie was one-of-a-kind... brilliant, original. Funny and emotionally fearless," he said. "She lived her life, bravely... My thoughts are with her daughter, Billie [Lourd], her mother, Debbie [Reynolds], her brother, Todd [Fisher], and her many friends. We will all miss her."
