The Voice contestant Kevin Simm wowed all four coaches with a stunning rendition of Chandelier by Sia.
The Chorley-born singer auditioned before the all-star panel of will.i.am, Boy George, Paloma Faith and Ricky Wilson.
In the battle to land the ex-member of Liberty X, an explosive on-air argument erupted between Faith and Boy George.
The Culture Club singer reportedly made her cry after she pretended to fall asleep during his pitch for the one-time pop heartthrob.
An irritated Boy George snapped, "Excuse me, Palaver!" He then admonished his fellow panellist.
"That's extremely rude. Very rude," the 54-year-old said. "Anyway, you're amazing," he told Simm.
Wilson added: "It's just obvious when you hear a voice of that quality singing, you have to turn around."
Faith told the 35-year-old he was "phenomenal" and will.i.am said he just "wanted to listen" to him sing.
Simm ended up on Faith's team, despite Boy George pointing to her lack of success in America compared with his achievements.
Due to the harsh words exchanged, a source said BBC bosses had to tone down the episode to make it more family friendly.
Alongside Michelle Heaton, Tony Lundon, Jessica Taylor and Kelli Young, Simm failed to make it into Popstars winning group Hear'Say, whose members included Myleene Klass and a pre-Coronation Street Kym Marsh.
Liberty X's Just A Little won a Brit award for best British single in 2003.
They enjoyed several more hits before calling it a day in 2007, but the band out-lasted Hear'Say, who had split in 2002.
Earlier in the show, Faith struck gold with student Aliesha Lobuczek.
The 17-year-old's rendition of Break Free by Ariana Grande had also amazed Wilson and Boy George.
Contestant Alaric Green graduated from the London School of Musical Theatre and toured Europe with The 12 Tenors.
The 21-year-old bouncer, who lost nine and a half stones in two years, auditioned to Broken Vow by Josh Groban.
Wilson and will.i.am's chairs turned, but the American later admitted he had accidentally hit the buzzer so it was no surprise when Green chose the Yorkshireman.
Faheem, from Bradford, impressed both will.i.am and the Kaiser Chiefs frontman with his version of Marvin Gaye by Charlie Puth featuring Meghan Trainor.
The 21-year-old had barely started his audition when will.i.am's chair turned. Wilson knew he would struggle to land the Bradford-born singer, and his instinct turned out to be correct.
Auditioner J Sealy, 43, lost the hearing in his left ear last year and was bedridden for a few months.
The part-time personal trainer's version of The First Cut Is The Deepest was enough to secure his place on Boy George's team.
Voiceover artist Steve Devereaux plays Howie in CBeebies show Chuggington.
The 60-year-old impressed Faith when he took on Frank Sinatra's The Lady Is A Tramp. "I've found my father figure!" she cried.
A nervous rendition of the late David Bowie's Life On Mars by pop wannabe Heather Cameron-Hayes did not deter Boy George and Wilson.
"I'm always pleased when I hear someone really young singing a Bowie song," Boy George said as the 16-year-old decided to join his team.
At the end of the fourth week, will.i.am, Faith and Boy George have seven acts in total, while Wilson has six.
The Voice continues on BBC One next week.
