Twenty-one-year-old Lexie Alford might have become the youngest person to visit every single country in the world.

That's right, she claims to have visited 196 countries in 21 years - that's more than nine countries a year!

This means she may have smashed the the current Guinness World Record holder - James Asquith - a British man who achieved the same record at the age of 24.

Lexie credits her ability to travel at such a young age with hard work and a family who own a travel agency (well, that might help a little!)

Lexie finished her amazing feat in the very hard to access North Korea - it is thought she completed the journey in North Korea and South Korea's demilitarized zone - known as the DMZ.

This might cause contention for her record, which requires her to visit every single country, as some people do not consider the DMZ to be an official part of North Korea.

She announced her visit to the final country on her list on 31 May.

Along the way, she shared her journey with followers on social media.

Lexie says she was motivated "to show everyone that the world isn't as scary as the media portrays it to be and that there's kindness everywhere."
