Live Nation's Katy Perry X Factor Sponsored Tweet Faux Pas

If you're responsible for an international tour promoter's Twitter account, it may be a good idea to actually watch a singer's performance before using it as a marketing tool for their upcoming tour...

Katy Perry just had a screech-fest on the X Factor Live Final and Live Nation thought it would be a good time to sell some tickets for her forthcoming UK tour...

This was a perfect example of an ill-judged sponsored tweet.  An avalanche of tweets spewed forth... These are just a few from the first 4 minutes...  Enjoy... *bad language warning*

Quick! Get your tickets now! You'll be sorry when they're gone.
