Keith Urban and Nicole Kidman know how to keep the spark alive.
The country artist and award-winning actress, both 52, apparently celebrated Valentine's Day one day early by paying a visit to Dolly Parton's famous theme park, Dollywood, in Pigeon Forge, Tenn.
Urban posted a sweet photo of the pair posing together inside of a gigantic heart-shaped frame made of wooden logs.
"HAPPY VALENTINES DAY❤️🔥💋," Urban captioned the pic posted late Thursday night.
The couple was dressed down in matching knit hats and raincoats for a day of fun.
Kidman's "Big Little Lies" co-star Reese Witherspoon commented on the pic, calling the pair "Sweet hearts."

"I like to relax by meditating, but what makes me feel most comfortable and secure is being with Keith," she said of her husband, country star and fellow Aussie. "Having a partner by your side, someone with whom you can talk, who loves you and who you love, balances everything."
Kidman continued: "Before I met him, I was more scared. Now I feel protected thanks to this great friend and wonderful partner I have."
