Rosie Baldwin successfully broke the record for the Fastest time to type the alphabet on a touchscreen mobile phone.
When challenging this title, predictive text must be turned off and there can be no spaces or errors in the alphabet.
Rosie was worried her dyslexia would stop her from winning the record, but she managed an incredible time of 7.44 seconds – a nail-biting 0.16 seconds faster than she needed to secure the title!
"I knew I’d get it eventually!” she said, when she was presented with her certificate in front of a cheering crowd," she said.
However, the Guinness World Records Live! team will be at Cannes Lions until Friday – which means that someone else could beat her record and take the title!
