A Brazilian school is using celebrities to help its pupils learn English, but with a twist: it's the kids correcting the stars.
The Red Balloon school had children correct grammatical errors in tweets by stars such as Sylvester Stallone, Rihanna and Justin Bieber.
"New experiment of Red Balloon, to show Brazilian kids can speak English better than native speaker celebrities on Twitter!" the school said in a YouTube video
showing its "Celeb Grammar Cops."
In the video posted last June 10, the school said the experiment had children aged 8 to 13 checking their favorite celebrities' tweets.
The school said it decided to do something about the potential threat of social media to encourage bad grammar - it had the children reply to the celebrities.
"The kids would tweet back at the celebrities, explaining politely what was wrong in their tweets," Buzzfeed.com reported
Buzzfeed added these pupils appear "definitely the most polite correctors of grammar on the Internet, that’s for sure."
Some samples of the interactions between stars and the young grammar cops as compiled by Buzzfeed include:
1. Sylvester Stallone:
3. Daniel Radcliffe:
4. Kim Kardashian:
5. Paris Hilton:
Even young star Justin Bieber wasn't spared:
