Here's a recap of the contestants on The Voice UK in Team Jennifer Hudson who face the knockouts tonight.
Currently a total of 24 contestants remain in the competition but over the next two weekends they'll be whittled down to just 12.
Tonight sees the knockouts begin with Team Jennifer Hudson centre stage.
Every act from the team will head out to face the coaches, a live studio audience and viewers watching live at home.
One by one they'll step forward to perform what they hope is a killer song to get them through to the live finals.
All the coaches will have something to say before voting lines open.
The public will vote for their favourites and the two with the most votes will head into the finals.
That team's coach will then have an important decision as they select a third finalist from the four remaining acts in their team.
Team Jennifer is first up and her line up after the battles includes David Jackson, who will be singing A Little Respect by Erasure, and favourite to win Mo who has chosen Freedom by Beyonce as his song.
Jennifer's steal Tim Gallagher will be singing Want To Want Me by Jason Derulo while Georgie Braggins has selected I Say A Little Prayer by Aretha Franklin.
Finally, Jamie Miller is set to sing Ed Sheeran's new single Shape Of You and Jack Bruley will perform To Love Somebody.
The Voice UK airs live tonight at 8.30pm on ITV where Tom Jones will also be performing his classic You Can Leave Your Hat On.
The knock outs return live at 7.45pm on ITV on Sunday where Sir Tom Jones' team will sing and Jennifer will be performing.
