SPOILER ALERT: You may wish to avoid reading this story if you are waiting to watch The X Factor USA on British TV.
Britney Spears has made her live debut as a judge on The X Factor USA, and she described nearly all of the 16 finalists in glowing terms.
Britters, who could clearly be seen to be wearing earplugs, used words like "amazing", "incredible" and "entertaining" for all but two of the contestants - taking an early lead in the "most-positive judge" stakes.
And Britney even moulded one of her teenage charges in her own image, dressing young Carly Rose Sonenclar as a schoolgirl - complete with grey cardigan and tartan skirt - just like herself in her famous Baby One More Time video.
But it was new host Khloe Kardashian who may have stolen the show, stunning viewers by clearly showing one of her nipples through her sheer blouse as she made her debut on presenting duties alongside Mario Lopez.
After the show she tweeted: "I think I had a little nip action earlier LOL."
Only 12 of the contestants will go through to next week's show, with four being eliminated in tonight's results show.
And one of the acts, girl group LYLAS, have changed their name for legal reasons.
Simon Cowell said: "We have had a name change, for boring reasons. They're now 1432, which means 'I Love You Too'."
Digital Spy reports that a group called The Lylas - composed of Bruno Mars' sisters - had complained that the name was too similar to their own.
Britney appeared on Jay Leno's show earlier this week.
