Danny O'Donoghue, who already had his full squad of ten singers for the second round of the competition, jokingly told will.i.am, "I hate you" and sat hitting his unresponsive chair buzzer after hearing Ellington's audition.
Speaking about Ellington's first song, will.i.am claimed that it sounded like he has "fallen out of the sky". He later described the singer as a "beautiful angel".
Jessie J pleaded with the 28-year-old to perform a second track for the coaches and when he launched into his version of 'Ordinary People', both Jessie and will.i.am were overcome with emotion.
Earlier in the show, will.i.am had revealed how he wrote the track 'Ordinary People' with John Legend after the ending of a lengthy relationship. "It was about someone who looked after me when I was broke and poor," he said.

The Black Eyed Peas star lauded the final addition to his squad, commenting: "The dude's name is Jaz. His name isn't Phil. Like Phil the last spot in the team.
"His name exudes what he's supposed to do."
O'Donoghue said afterwards: "The reason this show exists is for moments like that. It was a really emotional time."
Backstage, Ellington described his audition as "the best experience I've had on stage".
The Voice UK continues next week with a double bill on Saturday and Sunday as the show enters the Battle Round stages.
