Quentin Oliver Lee has died aged 34, his heartbroken wife has announced.
The Broadway star, best known for starring as Phantom in the US tour of The Phantom of the Opera, died while holding onto her hand.
Writing on her husband's Instagram account, his wife Angie said: "Phantom in the US Tour of The Phantom of the Opera. I saw his last breaths, held his hand tight, and felt his heartbeat slowly drift away. He had a smile on his face, and was surrounded by those.
"It was peaceful, and perfect."
"He was an incredible man, husband, father, son, brother, friend, singer, actor, and disciple of Christ with great faith in his Father in Heaven. To say "he will be dearly missed" doesn't reflect the scope of the people and communities he has created and touched.
"If we let him, he made us better people. Samantha and I are supported and lifted by our families and our own faith. Please understand if I don't respond, but trust that your messages and love have been read and felt," Angie added.
Devastated Angie also shared pictures of her late husband holding their little girl on his lap and other sweet family photos.
Before his death, the Broadway star was named a Western Regional Finalist in both the Metropolitan Opera National Council Auditions and the National Association of Teachers of Singers Artist Awards.
The star also had some incredible career achievements under his belt, including performing as a 'soloist in Handel's Messiah with the Flagstaff Master Chorale, a guest soloist for the Sedona Opera Saloons, Soloist for the MLK Day celebration in Jax Beach, Florida, and as a performer at the Romanian Embassy in New York.'
Just six months ago, shared a photo of his hospital wristband after he was diagnosed with stage 4 colon cancer.
At the time, he penned: "I’m a father, husband, teacher, Broadway and Metropolitan Opera performer and soon to be cancer survivor. It is definitely difficult to make money performing while also going through chemo, surgeries and dealing with these messy cancer symptoms that may drag on for who knows how long.
"All of you have already show your love and support in so many ways. Know that, any donation will help us pay medical bills, keep the lights on, keep food on the table, and help Angie and I stay focused on beating this disease instead of worrying about how we can meet our needs."
Back in June, the star and his family created a GoFundMe to help fund his treatments, including chemotherapy and surgery.
Overall, 465 donors raised $43,948 for his medical expenses.
