Japanese pop star Seiko Matsuda has had an incredibly successful career, and is even known as Japan's "Eternal Idol" since releasing 24 consecutive number-one singles in just eight years back in the '80s. But, Seiko's music isn't the only thing that's eternal — it appears her youth is, too! Seiko recently released a cover of her hit song "Blue Lagoon," and the singer looks so youthful, people initially thought the woman in the video was her daughter. Nope, it's the 59-year-old herself! We'll have whatever Seiko's having.
