What does that spell? Iconic.
Alongside a selfie of herself smiling as she showed off an emblazoned green and yellow jacket with her name on it, Jessica captioned her Jan. 3 post, "Found my 8th grade head cheerleader letter jacket."
And we're not the only ones who found the post sweet.
Another person who celebrated the ode to the past was Paris Hilton, who dropped a single heart eyes emoji.
The "With You" singer's post comes just a few weeks after she shared a series of snaps of her family getting in the holiday spirit.
In photos of herself with husband Eric Johnson and kids Maxwell Drew, 10, Ace Knute, 9, and Birdie Mae, 3, Jessica, captioned a Dec. 19 post, "Faux-sure feeling festive with my beautiful family in this Holiday Season."
Before Christmas rolled around, her brother-in-law Evan Ross gave a sneak peek into what their holidays look like together as a big family.
"We always have traditions but I'm going to be with my wife's family for Thanksgiving," Evan said in an exclusive interview with E! News in November, "then we go to see my family on Christmas—but the holidays are always amazing."
He added, "All the cousins together. All the kids loving each other and having a good time. It's a blessing."
Ashlee and Evan are parents to Jaggar Snow Ross, 7, and Ziggy Blu Ross, 2, while the "Pieces of Me" singer is also mom to Bronx Wentz, 13, with ex Pete Wentz.
