At one point, he turned for 25-year-old Jess Hayes alongside his three other coaches - will.i.am, Olly Murs, and Anne Marie - although he missed out on landing her on his team thanks to Murs.
And during the show's final performance by 33-year-old Jazz Morley - who it transpired supported the 83-year-old at a 2019 gig - Jones turned his chair and bagged her as a singer on his team.
However, it's what Jones said to the penultimate performer of the evening, Zaza, which left fans scratching their heads.

Jones refused to turn for Zaza but will.i.am swooped in to save her from a dreaded exit from the contest.
Just moments before he was shown turning for Jazz on-screen, Jones told Zaza why he refused to smash his button.
"The reason that I didn't turn is because I've got a lot of girls on my team but that's the only reason honestly, I loved what you did," Jones told The Voice contestant.
But moments later after he turned for Jazz, several X users shared their bemusement at Jones deciding he wanted another female on his team all of a sudden.
One X user fumed: "I thought Tom said he didn’t turn because he had enough girls. Then he turns for the next girl. I’ll never work out the logic of this show #makeitmakesense #TheVoiceUK."
A second weighed in: "#TheVoiceUK So Tom Jones tells a female singer she had a great voice and would have turned if he did not have so many females in his team. Then turned for the very next female."
While a third also spotted the odd reasoning: "Tom Jones told the previous lady he can’t take her because he has ‘too many girls’, but he just took another one? That’s not right. #TheVoiceUK #tomjones #thevoice."
However, a fourth person blamed the ITV production team rather than Jones: "#TheVoiceUK the only reason I didn’t turn was because I’ve too many ladies on my team said Tom!
