I don’t know who could confuse Mariah Carey with Marie Curie (maybe spell-check), but this birthday cake fail for a Mariah fan led to a funny birthday shout out!

This was the tweet that started the conversation about the birthday cake snafu…

The tweet eventually made it to Mariah and Siobhan ended up getting a birthday shout out from Mariah, so that’s probably even a better birthday gift than a Mariah cake!
