It's round two of The Voice UK knockouts this weekend and the acts are going all out to win over their coaches.
This SUNDAY night will see Team Will.i.am and Team Boy George's final line ups confirmed as each of the coaches picks just three acts to make the live shows.
Before the coaches have to decide, all of the eight singers in their teams have one last performance to prove why they should be taken through.
For her song, Lydia is taking a big gamble.
Will.i.am says of the Essex performer: "Lydia not only sings good, I believe Lydia's the full package, she's a powerhouse."
"I was nervous going in there with Will and I just want him to like me," Lydia says of her rehearsals. "When I told Will what the song was, he sort of looked at me like 'What?'
"I'd say I'm taking a risk with this song because I've completely changed it up."
Will teases that Lydia has changed the song so much, it's like a completely different track.
"I'm like wait a second, they don't sing this song, wait a second, yes they do, [but] they don't sing it like that!" he says.
But Will also warns: "It's up to Lydia to live up to what's in my head because she can totally mess it up, what's in my head is perfect."
Another act going all out in the knockouts is Lyrickal who lives up to his name as he pens his own lyrics as part of his performance.
He says: "I want to tell my own story."
Meanwhile, an "emotionless" Eli Cripps is told by Will that she needs to let it all out on stage with the Black Eyed Pea star wanting a "hot and steamy" performance.
Others in Team Will are Charley Blue, Lauren Lapsley-Browne, Faheem, Tom Rickels and Theo Llewellyn.
The Voice UK airs this SUNDAY night on BBC One from 7:45PM.
