15 years after the release of the smash hit film 13 Going on 30, Jennifer Garner paid tribute to the movie on her Instagram.

“Fifteen years ago today #13GoingOn30 made her debut, directed with ❤️ by our beloved Gary Winick 😇 and a clutch of loving, hardcore producers (3 brilliant women—before it was cool to be led by women!),” Jennifer posted.

“The movie benefitted from the performances of so many young actresses. Open and twinkly-magical then— now, 15 years later, they are ruling the world. (Hi #SixChicks—@brielarson, @ashleybenson, @christabrittany—who also played a young me in Ghosts of Girlfriends Past—and my own sweet @revjuliaroth),” she continued.

“I loved my day with this slumber party crew: they danced with abandon and reminded me of the power of just saying yes—to being in a group, to vulnerability, to wearing a bra over your clothes. At the last minute, I tossed my adopted LA family member Maddy Sprung-Keyser into the scene. @maddsk went on to be an Academic All American swimmer at Amherst, got her law degree from NYU, and is producing podcasts for @pineapple.fm. Looking back into her adolescence—with the hair and the men not wanting to jump her bones—is extra special today. Imagine if every 13-year-old girl had an opportunity to dance and feel beautiful like the girls in this film. I am proud of all of you,” Jennifer added.

Garner concluded, “I feel so, so lucky to have had the experience of making this joyful movie. And even luckier to be part of something that, all of these years later, can still make people (hi, @arianagrande 🤗) smile.”

In November 2018, Ariana Grande paid tribute to 13 Going on 30 in the music video for “Thank U, Next” by honoring the emotional climax of the film.

After a very rough 2015 due to her divorce from Ben Affleck and the nanny drama, Jennifer started the new year off on a pretty good note. In January 2016, Jennifer took her son, Samuel Garner Affleck, out in Brentwood on an afternoon to play.

Jennifer wore a chambray top layered underneath a sweater. The then 43-year-old paired her tops with black jeans and Isabel Marant tassel boots. She kept her eyes hidden behind a pair of sunglasses.

The actress was all-smiles as always as she returned a runaway ball to a kid, and was later on seen carrying a sleepy little barefoot Samuel.

We’re not sure who her new mystery man is, but the two were spotted talking in his car for a good thirty minutes. Reports say the man is the family’s accountant. Prior to the sighting, rumors of Jennifer Garner getting together with Patrick Dempsey were afloat.

Jennifer’s Isabel Marant tassel boots are from a collection a few years back and are now sold out online.
