The members of K-pop girl group Red Velvet threw a surprise birthday party for the group's leader IRENE.
On March 29, Red Velvet posted a short video clip on its social media account.
In the video, the members of Red Velvet waits for IRENE with her birthday cake in a room.

Then, a smile starts spreading on her face.
The video clip ends with IRENE about to blow out the candles on the cake.
Ever since the video clip was uploaded, fans have been commenting on how cute IRENE's reaction was.
IRENE was born on March 29, 1991, and she has turned 27 today.
