The Star Wars family is taking the death of Carrie Fisher hard.
Adam Driver appeared on The Late Show With Stephen Colbert on Thursday, where he talked about the death of the legendary actress. Driver's Star Wars character, Kylo Ren, was revealed to be the son of Princess Leia (Fisher) and Han Solo (Harrison Ford) in 2015's Star Wars Episode VII: The Force Awakens.
"As you can kind of tell from meeting her, she burns very bright and has such a great, very generous energy," Driver said. "For that suddenly not to be on set, or we're talking about it in publicity or just in life, when you kind of see her around at a Star Wars event, or anywhere, to have... her character -- not just her character in the movie, but her character missing from that very small unit -- is a tragedy."
Driver, 33, said the last time he saw Fisher was on the set of Star Wars: Episode VIII, which comes out in December.
"We finished the second one last summer," he revealed. "I think that was the last time I saw her, actually, on set being Princess Leia."
Driver's The Force Awakens co-star, Daisy Ridley, also commented on the death of Fisher last month. "Devastated at this monumental loss," Ridley, 24, said in a statement to ET. "How lucky we all are to have known her, and how awful that we have to say goodbye."
A private memorial for Fisher was held on Thursday at her home in Beverly Hills, California, with Meryl Streep, Gwyneth Paltrow, Meg Ryan, Courtney Love, Ed Begley Jr. and Ellen Barkin in attendance alongside Fisher's brother, Todd Fisher, and his wife. Fisher's daughter, Billie Lourd, was joined by her Scream Queens co-star, Taylor Lautner.
