Idk if anyone cares about lipsync songs being spoiled for season 11, but apparently these are used:

Spoiler:

Miley Cyrus - Best of Both Worlds - allegedly episode one, and she's a guest judge. There seems to be more tea about her being on, than which song is used, as some claim it's "Can't be Tamed".
La Roux - Bulletproof
Jennifer Lopez - Waiting for Tonight
Belinda Carlisle - Heaven is a Place on Earth
Dua Lipa - New Rules
No Doubt - Just a Girl
Madonna - La Isla Bonita
Sonique - It Feels So Good
France Gall - Ella, elle l'a
Nelly Furtado - Maneater
Charli XCX - Superlove
Annie Lennox - Walking on Broken Glass

To be taken with a pinch of salt, though, since 'lipsync song choices' are always the least reliable leaked information lol. Was gonna post this in the "songs you'd like to see" thread but it might've spoiled it for some.
