Nicole Scherzinger ended up nabbing the full-time job for the Live Shows, but Rita Ora, Spice Girls Ginger and Scary, Leona Lewis and Anastacia were among the superstars who filled on the audition tour. But who was the best?
Mel B caused a storm in week one with her feisty put-downs and no-nonsense attitude and has grabbed the most screen time across the series.
Geri Halliwell, ever the shrinking violet, rubbed her co-stars the wrong way and took over the show last weekend. Meanwhile, former Leona Lewis managed to hold her own while Eddy String rocked out on the stage (and the judges' table) and she even won the Head Judge title off Gary Barlow and Louis Walsh on The Xtra Factor.
Rita Ora and Anastacia have featured far less, with the latter only getting a blink-and-you'll-miss-it cameo so far, but neither embarrassed themselves on the talent show.
