is just a girl, standing in front of , professing her love for her husband.

On Tuesday, the actress posted a throwback photo on the social media site of her and her cameraman husband, Daniel Moder, kissing. She captioned it, "21" and added the hashtags "truelove," "heckyeah," and "fromhereonout."

The couple tends to keep their love private, but their anniversary is a special event where Julia shares photos of the two locking lips.

Last year on 4 July, Julia posted another throwback on Instagram, this time captioning it "TWENTY" with the hashtags "can'tstopsmiling" and "can'tstopkissing" along with some emojis.

Each year, Julia has done some form of anniversary post since joining Instagram in 2018.

Usually its a photo of the two, except for 2019 where she posted a photo of her wearing an shirt with a photo of her husband as a child riding a bike. She used the hashtag "Thewheeliekingswife."

Also, in 2018, she wished the world a happy Fourth of July while throwing in that it was her 16th wedding anniversary as well.

Daniel is an accomplished cameraman, having been nominated for a Primetime Emmy for Outstanding Cinematography for a Miniseries or Movie in 2014. His filmography includes Mr & Mrs Smith, 2015's Point Break remake, and Mona Lisa Smile.

Daniel and Julia met while filming the movie The Mexican in 2000. The two were coupled up with other people, but eventually found their way to each other and were married in 2002 at Julia's ranch in New Mexico.

Together the couple has three children, twins Hazel and Phinnaeus born in November 2004 and Henry born in June 2007.

Julia has an obvious love for her family, posting an old photo of her dad for the most recent Father's Day and always wishing her children happy birthday.

Her Instagram is also filled with praise for her fellow actors and stylists, along with calls for equality and gun rights. Last month she did a Gucci campaign to "Chime In" for gender equality featuring Idris Elba, John Legend, Salma Hayek, and more.

Wishing the couple many more years of happiness!
