Jessie J reckons that Will.i.am is her biggest completion after all four coaches completed their teams this week.
Jessie, Will, Danny O'Donoghue and Sir Tom Jones have all chosen their ten acts and there's no going back now.
There's been fighting over the acts, and even some bitching, with Will, Danny and Tom all thinking Jessie had made a mistake by picking Ruth Ann St Luce.
But Jessie confessed of all the coaches, it's Will and his acts she fears the most.
While the 23-year-old Price Tag singer managed to win the likes of Becky Hill, Indie and Pixie and Vince Kidd on her team, Will was pickier with his choices.
The Black Eyed Peas star was the final coach to make his selection, and waited right until the end to pick Jaz Ellington.
Will also has J Marie Cooper, Joelle Moses and Kate Read in his group.
This Saturday and Sunday it's a double helping of The Voice, as Will, Jessie, Danny and Tom all take on the unenviable task of deciding which five singers to ditch, and which five to take through to the live rounds.
