A total of 24 contestants were left in the competition at the star of the weekend but over the next four live shows they'll be whittled down to just 12.
Last night saw the knockouts begin with Team Jennifer Hudson centre stage and tonight it's Team Tom's turn.
Just like on Saturday, 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.
Sir Tom and the other coaches will offer their opinion before voting lines open for fans to support their favourites.
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 hey select a third finalist from the four remaining acts in their team.
Team Tom is next up and his line up after the battles includes Craig Ward singing Hold On Tight by Greg Holden and Nadine Mcghee performing Secret Love Song by Little Mix Ft. Jason Derulo.
Also singing tonight are Dannii Barnes who will belt out False Alarm by Matoma & Becky Hill and Sir Tom's battle round steal Victoria Kerley who's singing Find Me by Sigma Ft. Birdy.
Finally on Tom's line up for the knock outs are his two duos, Capital B and Into The Ark who are singing One Day I'll Fly Away by Randy Crawford and Hold On, We're Going Home by Drake Ft. Majid Jordan respectively.
The Voice UK airs live tonight at 7.45pm on ITV with the live knock out rounds, including a special performance from Jennifer Hudson.
The knock outs return live next Saturday night on ITV with Gavin Rossdale and Will.i.am.
