Kelsey Grammer, Jamie Lee Curtis and Other Stars React to Kirstie Alley's Death: 'You Were One of a Kind'

Hollywood is remembering Kirstie Alley after her death.

On Monday, True and Lillie Parker, the two children of the Cheers alum, announced that the Emmy-winning actress had died from cancer. She was 71.

As news of her death circulated, many stars shared tributes for Alley to PEOPLE and on social media.

In a statement to PEOPLE, Alley's Cheers costar Kelsey Grammer said of the news: "I always believed grief for a public figure is a private matter, but I will say I loved her."

Fellow Cheers stars Ted Danson and Rhea Perlman also expressed their sadness in statements to PEOPLE.

"I was on a plane today and did something I rarely do. I watched an old episode of Cheers. It was the episode where Tom Berenger proposes to Kirstie, who keeps saying no, even though she desperately wants to say yes. Kirstie was truly brilliant in it," Danson said. "Her ability to play a woman on the verge of a nervous breakdown was both moving and hysterically funny. She made me laugh 30 years ago when she shot that scene, and she made me laugh today just as hard. As I got off the plane, I heard that Kirstie had died. I am so sad and so grateful for all the times she made me laugh. I send my love to her children. As they well know, their mother had a heart of gold. I will miss her."

Added Perlman: "Kirstie was a unique and wonderful person and friend. Her joy of being was boundless. We became friends almost instantly when she joined the cast of Cheers. She loved kids and my kids loved her too. We had sleepovers at her house, with treasure hunts that she created. She had massive Halloween and Easter parties, and invited the entire crew of the show, and their families. She wanted everyone to feel included. She loved her children deeply. I've never met anyone remotely like her. I feel so thankful to have known her. I'm going to miss her very, very much."

Alley's friend and fellow Scream Queens alum Jamie Lee Curtis shared a photo of the two from the Fox series on Instagram.
