“That’s my mood forever too (me back there),” Kourtney commented on Kim’s Instagram post

Kim Kardashian has been jamming out her entire life.

Just days after dancing to Usher at the Super Bowl during his halftime show, the 43-year-old mother of four posted a photo on Friday of her younger self rocking out in bejeweled sunglasses and fringe boots.

Some of the SKIMS founder’s 364 million Instagram followers immediately noticed someone lurking in the background of the photo: sister Kourtney Kardashian, 44, who quickly commented on the post.

“That’s my mood forever too (me back there),” Kourtney wrote, a play on Kim’s caption of “mood forever.”

Kim last shared a throwback image four weeks ago, and in that photo, Kourtney also stood behind Kim as the two siblings spent time with their late father, Robert Kardashian Sr., who died at age 59 in 2003.

In the latest throwback photo, it appears Kim is snapping as she strikes a pose in front of 1980s-era floral wallpaper.

Kim’s carefree vibe and youthful appearance in the photo reminded some followers of the four children she shares with ex-husband Kanye West: North, 10, Saint, 8, Chicago, 6, and Psalm, 4.

“That’s Chicago’s twin 1000%,” one fan wrote, while another commented, “That’s where Saint got it from 😂.”

Hulu’s The Kardashians returns for season 5 sometime in spring 2024.
