Little Mix: The Search continued on Sunday as Jesy Nelson, Perrie Edwards, Leigh-Anne Pinnock and Jade Thirlwall auditioned their sixth and final band.
The girls have already put together a mixed group, a boy group, a girl vocal group, a vocals and instruments group, and girl dance group.
Their final group will be rap and R&B style, and auditions kicked off with Manchester-born brothers Kyrome and Fabian.
The duo performed a cover of Robyn's heart-wrenching song Dancing On My Own.
Jesy and Leigh-Anne were utterly overcome with emotion as the boys sang, and both burst into tears as they watched.
One viewer tweeted: "Leigh-Anne crying makes my heart, let me hug her".
Another added: "lesy crying is too much i just wanna hug them".
"NO JESY AND LEIGH ARE CRYING IM GONNA CRY TOO," exclaimed a third.
"Jesy and Leigh crying just got to me, bless them so much," added a fourth.
Jesy told the brothers: "I just love how raw and honest you guys are, I love how when you sing you still have your accents.
"It's really cool, not many people have that, it brings a real different flavour to you guys.
She added: "The rapping is brilliant, the beat boxing, I don't know why you made us cry, something about you is really infectious."
Leigh-Anne gushed: "It's just real, these shows needs real people, I just feel so emotional right now, I don't know even why.
"The moment you started I was drawn in and I love your chemistry.
"I am a bit speechless right now, I loved that audition."
