Have you ever read a tweet, blog or Facebook post by your favorite celebrity and were completely baffled by their horrendous spelling and grammar?
Thankfully, there's a group of school children -- that's right, children -- who are tackling the problem head-on.
Students from the Red Balloon School in Brazil have set up a Twitter account, where the students respond to celebrities' tweets and correct their spelling and grammar.
"We have celebrities that are not really worried about the language," says school coordinator Andrea Baena.
Justin Bieber, Kim Kardashian, Katy Perry and Paris Hilton are among those who have received Twitter critiques from these clever youngsters.
@katyperry I'm Laís, 10 years old. Did you mean "I've just watched what looks like a 7 year old girl making..."? Kisses from Brazil.— Red Balloon (@redballoonBR) April 22, 2013
