Celebrity Twitter: Stars Who Adhere To Grammar And Spelling Rules, And Some Who Really Don't (INFOGRAPHIC)

By now we know some celebrities get major moolah to tweet on the behalf of companies, so you'd at least expect them to get the language part down, right? Interestingly, that's not always the case.

Grammarly, a premier writing enhancement app, decided to take a look at the top 150 celebrities on Twitter to see how they fare language-wise. Looking at each celebrity's last 25 tweets, Grammarly checked their grammar and spelling and counted errors per 100 words.

Surprisingly enough, sisters Kim and Kourtney Kardashian -- who get plenty of flak for the way they talk -- come in at a tie after President Obama, in terms of tweeterers who make the least amount of mistakes. With 1.6 mistakes per 100 words, the reality duo have a better command of the language than Bill Gates and the Dalai Lama.

Snoop Lion and Wiz Khalifa make the most errors (whether on purpose, using slang or simply cramming thoughts into 140 characters, it isn't specified), just a few more than the Kardashians' young sister, Kendall.
