BLACKPINK's Jennie showed support and love for fellow member Rosé's first solo album 'Rosie.'

On December 6, Jennie took to Instagram to share a heartfelt message to Rosé. She wrote, "I'm soooooo proud of you Rosie. Your album is so heartbreaking, beautiful, and warm. Makes me miss you very much. Can't wait for the world to hear your album. Love you. Your number one girl."

Fans were touched by Jennie's support for Rosé and revisited Jennie's post when Rosé released her solo track "On The Ground." Even during that time, Jennie wrote, "Your number one fan girl," expressing her affection for Rosé.

Fans are loving the close friendship the BLACKPINK members share with one another. Korean fans commented:

"In the meantime, teasing her about the kiss scene has been so consistent since 'Playing With Fire'—it's too cute… LOL. I really want to take a peek at BLACKPINK's group chat. Jennie even left a comment on Rosé's Instagram before leaving."
