Jennifer Garner attends the premiere of Netflix's "Family Switch" at AMC The Grove 14 on November 29, 2023 in Los Angeles, California.

Jennifer Garner is taking to social media to pay a very special tribute to someone very close to her heart, that being Nicole King Solaka.

Nicole is a founding partner at Linden Entertainment and has been one of Jennifer’s longtime managers, and in the past few years of partnership, they’ve become close friends.

In honor of her birthday, Jennifer, 51, took to her Instagram with a few photos of herself with her friend, some from more casual outings, while a pair of others represented their more glamorous side.

The lead photo of the tribute was a behind-the-scenes photo from the 2018 Academy Awards, when she wore a royal blue Atelier Versace gown with an exposed bodice and sweeping train, while Nicole wore a sleek black gown.

The photo set was closed out with another Oscars shot, this time from the 2022 ceremony, when Jennifer was dressed in a stunning off the shoulder Brandon Maxwell red-hot gown, while Nicole posed in a black column gown with white straps.

The Yes Day star sweetly captioned her post with: “My GIRL has a birthday today. 24 years of friendship, mothering, dreaming up nonsense and making it happen together.

“I am proud of you, @nksolaka, proud of your beautiful girls, my beloved goddaughters. I’m proud of your boss lady status with @lindenentertainment. I’m proud of our friendship and partnership and I love you. Happy Birthday!”

That dress! Blue is stunning on you!” A third also added: “That blue dress!”

She cited some of his former romantic on-screen leads like Gwyneth Paltrow, Jennifer Aniston, Keira Knightley, and Reese as well, wondering if they also believed he owed his “rom-com success to the scruffy hair, the untucked cute button down, both of which became like the norm for cute guys everywhere for the next 20 years.”

Jennifer joked: “I wonder if these esteemed ladies enjoyed Mark’s anxiety as much as I did. I wonder if he tried to drop out of their films, like he did out of ours after the first rehearsal of the ‘Thriller’ dance where Mark went from kind of shocked that we actually had to do this, to antsy, to deathly quiet, to ‘Bro, this is not for me.'”
