John Legend can't help but show all of his love for wife Chrissy Teigen.

The "All of Me" singer ended the weekend with a sweet appreciation Instagram photo of the entrepreneur wearing a slinky black dress and stiletto sandals. The snapshot showed Teigen playing with her hair while she posed on a balcony overlooking the waters of the French Riviera.

"Beauty on the Côte d'Azur. Thank you @jazzajuan for a wonderful time! Thank you @chrissyteigen for being fine AF," Legend, 43, captioned the post, which also included a landscape snapshot and a backstage photo of the singer at the Jazz à Juan musical festival in France.

Teigen, 36, also posted the photo on her Instagram where Legend couldn't help but show his admiration in the comment section, writing "Fine AF," again.

"A night in Nice. Stockholm tomorrow!" she captioned the post while also asking her followers for kid-friendly recommendations in Sweden.

The couple have been documenting their vacation in Europe with their two children Luna, 6, and Miles, 4, while Legend has been performing gigs at multiple European music festivals.

Among the cute photos of Luna and Miles exploring the continent, Teigen has been serving many looks on her Instagram.

Last week, the mom of two shared an airplane selfie as the family of four made their way to Italy where Legend danced and sang his way through the Lucca Summer Festival on July 9. She sported effortlessly tousled waves and a denim top.

She also shared a photo of herself wearing a rustic white dress with flowing tiers and an elegant updo in Italy. It also caught the eye of actress Mindy Kaling who commented, "I mean this as a compliment, this looks like the best European pharmaceutical commercial for an anti depressant."

For her adventures in Amsterdam she donned a Western-chic denim dress, a pair of ruched cowboy boots and mermaid waves styled with braids throughout.

In May, the couple spent some time across the pond in the United Kingdom — and brought the heat with their couple moments.

In a photo carousel shared to Teigen's Instagram, she showed off her model legs in a black figure-hugging dress with a split that extended to her waist and a pair of strap stilettos heels. The post also featured Legend (who sported loafers and a brown suede trench over a polka dot shirt and trousers) fixing her hair while she looked back at the camera.

In April, the family also spent the day at Disneyland where they celebrated Luna's birthday decked in colorful ensembles — Legend wearing a vibrant Hawaiian floral-print shirt, Teigen sporting a neon green sports bra-legging set, Miles wearing a tie dye two-piece and the birthday girl rocking a Aladdin Jasmine costume.
