But while we're excited to hear more from them and other singers, the focus of the show will likely return to the judging table next week. That's because Ellen DeGeneres debuts as a panelist on Tuesday night.
Asked about her co-star by Entertainment Tonight, Ellen recently said: "He's actually meaner than I thought. It's hard to listen to him tell people things and me not to go, 'You poor thing!'"
Despite this critique, and despite rumors that she and Cowell are already fighting, an insider says everything is fine between the pair.
Yes, Simon appeared late at a taping last month, but apologized and DeGeneres "accepted it right away and was fine," says the source.
So, can Ellen offer any spoilers about which contestants make it far in Hollywood? No, but she does tease: "We have a wide variety [of talent]... somebody for everybody, I hope."
She's already getting good at this marketing game. Are you excited for her to take part on the show?
