After Knoxville worship leader Chris Blue’s Battle Round on Season 12 of “The Voice,” coach Blake Shelton predicted Blue would win the show.

During the show’s finale on Tuesday, that prediction came true.

“Voice” host Carson Daly announced Blue as the winner as confetti fell from the ceiling, and his journey on the show came to a close. Blue embraced his coach, Alicia Keys, and sang his original song "Money On You."

Team Blake Shelton's Lauren Duski placed second, and it was one of the closest voting margins between two "Voice" finalists, according to Daly.

Team Blake's Aliyah Moulden placed third, and Team Adam Levine's Jesse Larson placed fourth.

Blue expressed his feelings toward Keys before the winner was revealed.

"I tried to write something down, but my hands are shaking so I couldn't write, but I feel like it was destiny for us to meet. I feel like we were supposed to be in this moment together, and not only do I believe that I gained an amazing coach, but I really feel like you're my friend," said Blue.

Blue said he also would hold Keys to an earlier promise she made on the show, where she said that their performances together on "The Voice" wouldn't be the last time they sang together.

Before the winner was revealed, Blue and Keys talked about what it would mean to them if he won the show.

"Winning this show for Stephanie, my fiancee, would mean I didn't give up on her," said Blue.

"It would mean so much to see Chris win this," said Keys. "From being the last person that anyone turned around for, it would be such a win."

Blue also tweeted out support for Duski, Moulden and Larson.

Blue is the second “Voice” contestant to make it to the finale in the past few years. Knoxville teen Emily Ann Roberts received second place on “The Voice’s” ninth season in 2015, where Harlan, Kentucky, native Jordan Smith took first place.

Roberts congratulated Blue on Twitter after his win on the show.

During the finale, Blue performed a gripping cover of “Everybody Hurts" with Usher, who has served as a coach on the show in previous seasons.

Blue and Usher dedicated the song to anyone around the world who may be struggling, and it was a response to the tragedy in Manchester, England, where a suicide bombing killed 22 people and injured several more at an Ariana Grande concert.

The other finalists got to perform with celebrities including Duski with Little Big Town, Moulden with Alessia Cara and Larson with CeeLo Green. Some "Voice" Season 12 contestants who were eliminated earlier in the show returned to perform.

The Top 4 contestants also each received a 2017 Toyota RAV4 from the show.

Blue's 'Voice' journey

Blue started out his run on the show with a soulful blind audition, where he covered “Tracks of My Tears” by Smokey Robinson & The Miracles. He was the last to audition on the show and scored the last spot on Keys’ team, where he stayed during his run on “The Voice.” He won his Battle and Knockout Rounds against RJ Collins and Quizz Swanigan, respectively.

Throughout his time on the show, Blue covered songs both old and new. He wowed audiences with his rendition of Rihanna’s “Love on the Brain” and sang it in the same key that she does.

Blue’s covers of “When a Man Loves a Woman” by Percy Sledge, “Superstition” by Stevie Wonder and “Take Me to the King” by Tamela Mann also showcased his vocal talents, and his skillful dance moves that he employed in his performances of Bruno Mars’ “24K Magic” and Janet Jackson’s “Rhythm Nation” impressed the coaches and viewers.

He also got to perform twice with Keys. They sang a duet of Prince’s “Diamonds and Pearls,” and they and fellow Team Alicia members Vanessa Ferguson and Stephanie Rice performed "(You Make Me Feel Like) A Natural Woman" by Aretha Franklin. Blue described working with Keys as working with a big sister, and Keys challenged him to get out of his comfort zone.

The two talked about their time together on the show and their friendship in a confessional during Tuesday's finale.

"I wouldn't be here right now if it weren't for the musical genius herself, my coach, the best coach, Alicia Keys," said Blue.

"Chris is a super humble soul, and it's been an honor to not only coach him but to call him a friend," said Keys.

"My sons are 6 and 2, so when I see Chris, I think that they'll grow up with a beautiful soul, with drive like this and working hard. I love it," she said.

"They've got the right mom," Blue responded.

His motivation and inspiration

In a previous interview with the News Sentinel in March, Blue said he was motivated to try out for “The Voice” after his fiancée Stephanie Dunkley struggled with bone marrow cancer in 2016.

"When everything happened with my fiancée and her story, I realized that life was just too short," said Blue in the interview. "And after God was kind of pushing me to go forth, and I was declining and saying 'No. This can't be ...' I asked that He would just confirm, and He did, and when He did, I would say that really did help push me and helped me overcome the fear and just do it."

Blue has talked about his relationship with Dunkley, who lives in London, several times on the show, sharing bits of their love story and how she’s an inspiration to him when he sings. They met in the summer of 2014 and have had a long distance relationship since then.

Support from home

Knoxville has poured out support for Blue while he was on the show. Cokesbury United Methodist Church, Overcoming Believers Church, Knoxville Christian School and the Empty Cup coffee shop hosted “The Voice” watch parties so the community could gather together and see him on the show.

Before Tuesday’s finale episode, Knoxville Mayor Madeline Rogero announced on Twitter that the Henley Street Bridge would feature blue lights in support of Blue.

Blue's beginnings

Blue moved to Knoxville in August 2000 from Polk County, Florida. He attended and played basketball at Bearden High School and Knoxville Christian School. He went to Tennessee Temple University in Chattanooga and moved back to Knoxville in 2013 and started working at Cokesbury United Methodist Church not long after the move.

While growing up in Florida as the youngest of seven children, Blue found a love for music early in his life.

He and his siblings, two sisters and four brothers, sang together at gigs, and then he and his four brothers formed a group called the Blue Brothers. They performed at sporting events and birthday parties in Florida and on national TV on BET.
