Tom, will, Jessie and Danny have picked their teams of three, but only two can progress to the semi-finals. With plenty of shocks in the Knockout Rounds no act is safe, however, here at Digital Spy we have four clear favourites that we're going to be rooting for this week.
Joseph Apostol - Bookies odds: 9/1
The shy lad from the Philippines with a voice the size of a small African country. Not only does he have an incredibly cool mum, but he also managed to reduce Sir Tom to tears in the Battle Rounds. Who doesn't love The Big J?
Mike Ward - Bookies odds: 10/1
Simon Cowell may have got the wrong cousin. Former X Factor champ Shayne's younger cousin has been picking up a considerable fanbase thanks to his juxtaposition of hardman looks and heartmelting country vocals. But is the UK ready for a country music talent show winner?
Leah McFall - Bookies odds: 5/2
Her spellbinding vocal acrobatics in the Knockout Rounds have made Leah the bookmakers' firm favourite and it's easy to understand why. will.i.am has fallen head over heels for the kooky 23-year-old and if she can tone down the Jessie J-isms in her singing style, there's no reason she can't walk this competition. She's also the act with the greatest career potential.
Leanne Jarvis - Bookies odds: 10/1
We know they always bang on about how it's all about 'The Voice', but just for a minute, imagine if it wasn't. Imagine if style, looks, personality and charisma were important in being a popstar. Essex lass Leanne has all of the above. Oh, and her voice is pretty nifty as well.
