As BLACKPINK’s Rosé kicked off her birthday with a special surprise for her fans, BLINKs got the party started with a sweet and adorable gesture of their own!

Rosé officially turned 22 years old (by international reckoning) on February 11, and BLACKPINK’s fans celebrated the occasion by taking over Twitter. Shortly after midnight KST, the hashtag #RosesAreRosieDay and “Park Chaeyoung” (Rosé’s Korean name) began trending worldwide on the social media platform as fans came together to share their love for Rosé.

As of 1:10 a.m. KST, #RosesAreRosieDay was still the No. 1 worldwide trend on Twitter.

BLACKPINK’s official Twitter account also used the hashtag in its birthday post for Rosé, writing, “Today is our lovely and cute Chaeng-squirrel’s birthday. To all the BLINKs who are always a comforting source of strength [for BLACKPINK], please spend an exciting Monday full of love together with Rosé today.”

YG Entertainment and its founder Yang Hyun Suk also wished Rosé a happy birthday through posts on their official Twitter and Instagram accounts.

In return, Rosé shared her own message of love and gratitude for her fans, posting a cover of Halsey’s “Eyes Closed” and thanking BLINKs for their birthday wishes and support.
