Light bulb changes and no Jennifer Lopez music: Mariah Carey's list of demands for this London show will surprise you

Cape Town – According to The Sun Mariah Carey reportedly ordered the lightbulbs to be replaced backstage at the Royal Albert Hall ahead of her three-night stint at the London venue.

That's just the start of Mariah's long list demands though, according to a source: "Not only did they have to swap out the lights but everyone was told no music by Jennifer Lopez, Eminem or Nicki Minaj was to be played while she was there, because of her personal feuds with them.

The singer also reportedly requested a carpeted walkway from her car to backstage at the venue.
