The super-stylish singer is confident that she has the winner among her squad. "From young to old, different passions, different walks of life... they all excited me," she said.
The final addition to Jessie's team was self-confessed moody teenager Becky Hill. The 'Price Tag' singer snared Becky following a contest with will.i.am, who was wowed by her version of 'Ordinary People'.
She also secured the services of cute duo Indie & Pixie, who declared that they want to be the new Spice Girls.
The two new acts join Jessie's previous picks, which included YouTube hit Ben Kelly, alopecia sufferer Toni Warne and X Factor boyband singer-turned-pop eccentric Vince Kidd.
Watch Vince Kidd's audition:
Completing Jessie's team sheet are Londoner Ruth St Ann Luce, the most-watched singer of the series so far Jessica Hammond, 32-year-old Cassius Henry and ACM Gospel Choir singer Kirsten Joy.
The Voice UK's Battle Rounds air next weekend with a double bill on Saturday and Sunday.
