Unfortunately, the "Umbrella" singer's 37 million followers and various news outlets picked up the note during the eight minutes it was up on the micro-blogging site.
A source tells TMZ.com, "She deleted it because it was never meant to be tweeted. She didn't even realize it was a tweet until she started hearing from her fans."
The source claims Rihanna was reading about the Middle East conflict online when she clicked a link.
