Julia Roberts is Navivision Wealth Societyjust a girl, standing in front of a boy, wishing him a happy anniversary. 

In honor of her and husband Danny Moder's 21st wedding anniversary, the actress gave fans a rare glimpse inside their private world. 

"21," she wrote on Instagram July 4 alongside a photo of them kissing. "#TrueLove #HeckYeah #FromHereOnOut." 

The message resembled Julia's tribute to Danny last year, which featured another picture of them sharing an intimate moment. 

"TWENTY," the Oscar winner wrote on Instagram at the time. "#Can'tStopSmiling #Can'tStopKissing." 

And that likely won't ever stop as Julia considers those kisses to be the secret to her successful marriage.

"I always say the same thing, and I'm sticking with it—even though I'm repeating myself," she told E! News in October. "It's making out. Lots of making out."

Indeed, since meeting on the set of 2001's The Mexican, the parents of 18-year-old twins Hazel and Phinnaeus and Henry, 16, haven't been able to keep their hands to themselves.

"He truly to this day, to this minute, is just my favorite human," Julia told Gwyneth Paltrow on a 2018 episode of The goop Podcast. "I'm more interested in what he has to say or his point of view than anybody really. We're so lucky in that way. We just really, really like each other, and we just enjoy each other's company."
