Performers including Viola Davis, Selma Blair, David Arquette and Rosie O’Donnell honored “Heroes” star Hayden Panettiere, who died Sunday from an apparent overdose.

“What an amazing talent you were….so gifted,” Davis wrote on Instagram.

The pair worked together on the 2006 film “The Architect” and on 2016’s “Custody.”

“I wish the world had more time with you because I had a burning curiosity about who you were becoming,” Davis added. “I saw this beautiful Phoenix rising from the ashes. Your tests became your testimony, and your testimony became your legacy. You will be remembered.”

Panettiere’s father announced his 36-year-old daughter died on Sunday, but offered no details about what caused her death. TMZ said first responders in South Carolina performed CPR on an unresponsive female who may have suffered a drug overdose.

The 36-year-old actor’s “Nashville” co-star Brittany Shaw expressed shock over her former colleague’s death.

“This is a shock. Man, she was great,” Shaw posted on social media. “She had this way of making you feel at home. From the moment I walked onto the ‘Nashville’ set, she made me feel like I belonged. We had so many good times together, and I’ll always be grateful for them.”

Philanthropist and actor Selma Blair posted a photo of herself standing alongside Panettiere expressing sadness.

“Oh my god — heartbroken,” comedian Rosie O’Donnell posted on Instagram.

Panettiere’s “Scream 4” co-star David Arquette posted the cover of his colleague’s memoir “This Is Me: A Reckoning” on Instagram along with a note sending his love to her and her family.

“She was such a brave and brilliant soul,” he wrote.

Kelly Osbourne, who grew up on reality TV programming starring her heavy metal singer dad Ozzy Osbourne, mourned the loss of a friend she related to on Monday.

“We understood each other in a way few truly can — recognizing how difficult it is to grow up in the spotlight, and how isolating it can feel even when surrounded by so many people,” Osbourne posted on Instagram.

Panettiere’s first acting credit came in 1994 when she first appeared on the soap opera “One Life to Live.” She remained on that program until 1997, according to IMDb.
