Julia Roberts couldn't help but gush over her "true love" Danny Moder on their 21st wedding anniversary.

The "Pretty Woman" actress showered her beau with love in an emotional Instagram post on Tuesday more than two decades since they said, "I do."

Alongside a throwback snap of the pair sharing a kiss, Roberts kept the caption short and sweet.

"21," she wrote, adding the hashtags "#truelove," "#heckyeah," and "#fromhereonout." 

The lovebirds met on the set of "The Mexican" in 2000.

At the time, Moder was married to his first wife, Vera Steimberg, but after filing for divorce, he tied the knot with the Oscar winner on July 4, 2002.

The couple went on to welcome three children together: twins Hazel and Phinnaeus, 18, in 2004, and their son Henry in 2007.

While the pair tend to keep their personal lives out of the spotlight, they frequently profess their love for one another on social media on special occasions.

Last year, Roberts celebrated the couple's milestone wedding anniversary by posting a photo in which she passionately smooched the cinematographer as he caressed her face.

"TWENTY #can'tstopsmiling#can'tstopkissing," Roberts, who joined Instagram in June 2018, captioned the post.

Moder also expressed his deep affection for his wife with a throwback photo from before they wed.

"Today we start our 20th year of marriage. This photo was on a dusty road before that big idea … just holding on to this beautiful girl one day at a time," he captioned the post. "One epic day at a time."

The previous year, Roberts posted a similar message to her beau, writing "19 years. Just getting started! #conwings."

Last year, Roberts gushed over her "dream come true life" in an interview with "CBS This Morning."

"When I'm not working, [being a homemaker] is my full-time job," she said in October 2022. "It isn't rainbows and kittens every day, but it does bring me a lot of joy.

"The life that I have built with my husband, [and] the life that we've built with our children, that's the best stuff. To come home at the end of the day, triumphantly, to them."
