Happy Valentine's Day to the one and only Dolly and Carl!

Dolly Parton expressed her love for longtime husband Carl Thomas Dean on Valentine's Day on Monday.

Alongside a sweet throwback photo on Instagram of the couple where Dean, 79, kisses Parton on the cheek, the "9 to 5" singer, 76, wrote, "Happy Valentine's Day y'all!"

She continued, "Remember to squeeze your loved ones a little tighter today and tell them you love 'em! ❤️"

Last month, Parton revealed how she keeps her 55-year marriage "spicy."

"I like to dress up for Carl," the country star — who married Dean on May 30, 1966 — told E! News' Daily Pop. "Every day, I put on some makeup and fix my hair because I think, 'Well, the whole world, I'm out here and everybody else sees me all dressed up, and I'm not going to just kind of go home and just flop on him.' "

She added, "Nobody wants to make out with a slouch!" 

"It's important to me that I look as good as I can," the singer added. "I think it kind of helps keep things spicy."

She and Dean, who has long shunned the spotlight and never appears at public events with his wife, tied the knot after meeting in a Nashville laundromat.
