The Battle Rounds
The battle rounds were like Sing Star on a massive scale and unlike anything we've seen on a competition show before. The coaches, after picking 12 contestants each from the blind auditions, pitted two singers against each other to sing a duet. After the performances, the coaches had to pick one of the two contestants to go through to the live shows. One of the most talked-about (and hyped) battles was between Prinnie Stevens and best friend Mahalia Barnes (daughter of Jimmy). Their coach, Joel Madden, decided to go with Prinnie based on overall performance, even though his consulting mentor, twin brother Benji, thought Mahalia had a better voice.
