John and Charlotte Henderson were named the world's oldest living couple by Guinness World Records. Now, they're preparing to commemorate another incredible milestone.

On Dec. 22, the two lovebirds will celebrate their 80th wedding anniversary.

John, 106, and his 105-year-old wife, Charlotte, decided to recreate their first date, complete with a 1920s roadster as part of the festivities.

Of course, John didn't forget a bouquet of flowers to complete the nostalgic occasion.

John and Charlotte met in 1934 during a class at the University of Texas. John is also the oldest living former University of Texas football player.

The two eventually got married in 1939. And now, 80 years later, family and friends are gathering at their home in Longhorn Village in Austin, Texas to go through photos and relive cherished memories.
