Blake Lively, who worked with Michelle on "Gossip Girl," took to her Instagram Stories to post a lengthy tribute.

She wrote of Michelle, "She was electricity. You knew when she entered a room because the vibration changed. Everything she did, she did 200%. She laughed the fullest at someone’s joke, she faced authority head on when she felt something was wrong, she cared deeply about her work, she was proud to be a part of this community and industry as painful as it could be sometimes, she was fiercely loyal to her friends and brave for those she loved, she was big and bold and distinctly herself."

Blake added, "The world lost a deeply sensitive and good person in Michelle. May her work and her huge heart be remembered by those who were lucky enough to experience her fire.”

"Buffy the Vampire Slayer" co-star David Boreanaz wrote on his Instagram Story, "So very sad …horrible news. RIP and prayers to her and her family.”

Alyson Hannigan posted, "I am deeply saddened by the news of Michelle’s passing. She brought a loving energy to the set of Buffy. My thoughts are with Michelle’s family and friends."

Nicholas Brendon spoke out in an emotional Facebook video, sharing, "I think it was just the last thing I expected... I really am sorry to her family... I just wanna say that she'll be missed." He recalled their time together on the "Buffy" set and said she "was just always really happy."

James Marsters, who played vampire Spike on the show, told People magazine, "My heart is heavy today. We have lost a beautiful soul," he said. "Michelle was fiercely intelligent, howlingly funny, and a very talented person. She died much too young, and leaves behind scores of people who knew and loved her."

He added, "My heart goes out to her family who are good people, and are suffering the greatest loss anyone could bear. I hope everyone can give them space to heal in this most difficult time. Godspeed Michelle. You are missed."

Michelle’s “Gossip Girl” co-star Leighton Meester shared a tribute video on TikTok, including a montage of photos and writing, "Words seem so feeble in moments like these. Life is so precious, and death such a thief. The depth of your pain, I cannot comprehend, but I'll stand alongside you in the darkness, my friend. Love is a bond that death cannot part. Gone from your arms, but still held in your heart."

Ed Westwick wrote on his Instagram Story, “So sad to hear of the passing of @MichelleTractenberg Sending prayers.” 

Chace Crawford, who played Nate Archibald on "Gossip Girl," shared some throwback photos of himself with Michelle. He wrote, "Michelle was one of a kind. I remember her coming on set for the first time and just absolutely owning it. She was a force of nature and just so so unapologetically funny and magnetic.. remembering those years with a big smile. Just a terrible loss. Love you ❤️."

Melissa Gilbert, who starred with Michelle in the 1996 film "A Holiday for Love," wrote on Instagram, "Oh Michy…and we lived so close to one another…..my heart aches for your family and all those who loved you so…"

Trachtenberg’s rep Gary Montoosh confirmed her death, telling “Extra” in a statement, “It is with great sadness to confirm that Michelle Trachtenberg has passed away. The family requests privacy for their loss. There are no further details at this time.”

Michelle was found dead in an NYC apartment near Columbus Circle.

The NYPD later told "Extra," "Upon arrival, officers observed a 39-year-old female unconscious and unresponsive. EMS responded to the location and pronounced the victim deceased. Criminality is not suspected."

TMZ reports that Trachtenberg underwent a liver transplant within the past year and her body may have rejected it, causing complications.

Insiders revealed that Trachtenberg spent time with friends at Sartiano's in NYC, just days ago.
