Leo Ihenacho and Steven went next into the ring for Team Kylie after flirting with the Aussie singer in rehearsals.
It was a very evenly matched performance with the pair singing Thunder In My Heart by Leo Sayer, prompting Kylie to beg one of the other coaches to steal the loser.
The popstar revealed her decision to keep Leo in the competition and said: "They did again. They always get me out of my seat, it was so good! It was awful to put you together but it did bring something out of both of you. I'm praying there's going to be a steal after this."
Fortunately for Kylie, Sir Tom was quick to press his buzzer to pick up Steven for his own team's line up.
The Welsh crooner said: "Steven is too good to go, he's got a lot of promise.
"He's got the whole thing, he can sing and he can move."
