Earlier this week, Rihanna caused quite the online kerfuffle when she Tweeted #FreePalestine.
The singer quickly deleted the message, with sources somehow saying she didn't mean to send it in the first place.
We're not sure how that's possible, but we're are sure Rihanna isn't the first celebrity to get into trouble for posting on Twitter.
Heck, she wasn't the first celebrity to Tweet about freeing Palestine this month alone, with Houston Rockets center Dwight Howard writing the same words online before also taking them down.
What other stars have regretting getting into politics over the Internet? We rundown several cases below and come to the same conclusion each time: stick to acting... or singing... or whatever it is you do, Kim Kardashian.
Leave the politics to the politicians.
