A 21-year-old woman just pulled off an incredible feat  and earned herself a spot in the Guinness World Record book.

Lexie Alford just stepped foot on North Korean soil and became the youngest person ever to visit all 196 sovereign countries. She says the traveling to the countries was the easy part. Providing proof that she was there was the more difficult part.

She says Guinness required her to get signed witness statements from people in each country as well as provide receipts and passport stamps.

Alford says the achievement is something she’d been working on since she was a kid. Her parents owned a travel agency and often took her on trips around the world.
