BLACKPINK's Jennie and Jisoo showcased their close friendship through a sweet birthday post.

On January 8, Jennie shared a message on her personal account, saying, "It's late, but happy birthday, unnie. I dug out some old photos from our dorm days. We look great!" along with a heart emoji.

The photos featured their beloved pets, Dalgom and Kuma, both adorably gazing up at the camera.

In another post, Jennie shared a nostalgic memory, writing, "Remember how we used to go on walks together?" She also posted a photo of the dogs in a cart, adding a 'Happy Birthday' hat emoji on Jisoo's dog.

Their sweet interaction melted fans' hearts, highlighting the duo's strong bond.

Jisoo responded to Jennie's birthday post by reposting it on her account with a short caption, "Dal-Ku ❤️" (a nickname combining their pets' names, Dalgom and Kuma). She also added, "Let's go for a walk soon, Jendeukie," expressing her deep affection for Jennie.

On the same day, Jisoo shared a photo of a snack truck sent by BLACKPINK's Rosé, writing, "Tteokbokki, tteokbokki, tteokbokki… Thank you, our Chaengramji!" The post featured Rosé's hit song 'Apartment' as background music, which recently became a global sensation.

BLACKPINK, who renewed their contract with YG Entertainment and established individual labels last December, continues to pursue successful solo careers. Lisa, Rosé, and Jennie have all released well-received solo albums, while Jisoo is expanding her career as an actress.

Jisoo is set to star in the Coupang Play series 'Newtopia,' which will be released soon. During the press conference on January 8, Jisoo shared her thoughts on her fellow members' successes, saying, "The members are doing so well, and hearing about their achievements while I'm on set feels like it's happening to me too. It made me realize we really are like family, and it motivated me to work even harder on my projects."

Her words once again highlighted BLACKPINK's unwavering bond and mutual support in their careers, both as a group and as individuals.
