However, Britney cancelled because she was told she could not lip-sync, “There’s no way. Britney said she would only dance or lip-sync – and to be on stage with Cyndi, you have to actually perform. It’s not happening now.”
It’s probably for the best – Spears has come out of retirement a few times to guest-appear (dancing and lip-syncing) with the M+Ms, and it didn’t go down well with the audience.
A rep for True Colors said, “She was invited to appear on the first date in Las Vegas but we never heard from her.”
