Nick, who was diagnosed with the illness caused by the novel coronavirus in March and admitted to hospital on March 30, had been on a ventilator since then and gone through numerous complications and operations due to the condition.
"God has another angel in heaven now," his wife, Amanda Kloots, wrote on Instagram as she announced his death on July 5. "My darling husband passed away this morning. He was surrounded in love by his family, singing and praying as he gently left this earth."
Nick and Amanda married in 2017 and had a son, Elvis, in June 2019.
"I am in disbelief and hurting everywhere," Amanda continued. "My heart is broken as I cannot imagine our lives without him. Nick was such a bright light. He was everyone's friend, loved to listen, help and especially, talk. He was an incredible actor and musician. He loved his family and loved being a father and husband. Elvis and I will miss him in everything we do, everyday."
"I cannot begin to thank everyone enough for the outpour of love, support and help we've received this last 95 days. You have no idea how much you lifted my spirits at 3pm everyday as the world sang Nick's song, 'Live Your Life.' We sang it to him today, holding his hands. As I sang the last line to him, 'They'll give you hell, but don't you let them kill your light, not without a fight. Live your life," I smiled because he definitely put up a fight. I will love you forever and always, my sweet man."
Broadway and Hollywood stars mourned the 41-year-old on social media, with dozens posting about how deeply he had touched their lives and sharing how they had been struck by his kindness and generosity.
"Broken hearted and sending love to Nick's family," Sara Bareilles wrote in her Instagram Story that day. The two worked together on the Broadway production of Waitress, for which Sara wrote the music and lyrics.
"He was light. Kind and gentle. Talented and humble. Funny and friendly. The best laugh. Sending so much love to the love warrior @amandakloots and little Elvis, and an immense hug to anyone who is feeling the loss of this giant heart. Rest In Peace dear Nick. We love you."

"Devastating," Hamilton star Lin-Manuel Miranda tweeted. "What a loss, what a light. Whole heart with Amanda and his family tonight."
"Every person that I know who encountered this human was changed for the better and everyone that I knew that knew him I'm sure felt lucky to do so," he said. "I, like so many others, have followed @amandakloots stories every day hoping for a miracle. Sadly, this morning, Nick lost his fight against COVID-19."
"This virus does not discriminate," Steve continued. "It doesn't care bout statistics. My heart is shattered tonight for this man and his family and I beg you all to take this seriously and protect yourself and others. Wear a mask. We can beat this. We just have to have a little compassion for our fellow humans and stop being so selfish."
"For everyone out there thinking this disease is harmless, it's not," she wrote. "Amanda, because of this horrible disease we can't even hug you," the former Buffy the Vampire Slayer star wrote. "But it's important that you know, there is an army of people here, ready to support you in ANY and EVERY way possible. I wish you understood the inspiration that you have been to so many, and I hope that brings you even the smallest bit of comfort through all this. But none of this is fair."
Nick was born in Hamilton, Ont. in 1978 and went to Ryerson University for two years before he decided to pursue a career in show business. He began in a band called Lovemethod before moving to theatre with the Off-Broadway production of The Toxic Avenger. He landed his first Broadway role in Rock of Ages in 2012 and toured with the cast.
Nick found further Broadway success with Bullets Over Broadway two years later, and received a Tony Award nomination for the role. He was most recently known for his Broadway work in Waitress and A Bronx Tale. He had begun branching out into television work by appearing in Blue Bloods in 2017 and 2018.
After Nick was admitted to hospital in March, he was placed on a ventilator. He was in a medically-induced coma until May 12. During his time in hospital, he needed a leg amputation, a temporary pacemaker and Amanda had recently said he would likely need a double lung transplant and might never work again due to the disease.
Nick's hospital stay left the family with extensive medical bills. A GoFundMe has been set up to help Amanda and Elvis in light of his death. At the time of this writing, more than US$800,000 had been raised so far.
"I have a family. I have bills," Amanda said on July 2 as she spoke about how Nick was doing. "I have no idea what Nick's hospital bills are going to be. I haven't even tried to wrap my head around that yet. I have a mortgage. I have a car payment. I have a son that is one years old that I want to send to college one day, or at least give him what I can."
