Singer/actress Krystal celebrated her 28th birthday with some very special friends!

On October 26, a few days after her 28th birthday, Krystal shared a series of cheery photos from a birthday get together and wrote, "Hi everyone🫶🏻 I was a bit busy with 4 bday parties and still have 3 more to go😉 but yes I am so thankful for all the love I received from my family friends & fans!"

In her photos, Krystal appears happy as she poses in front of two candlelit birthday cakes. She's also seen posing with CEO Min Hee Jin of ADOR, the creator of NewJeans. Prior to her move to ADOR and HYBE Labels, Min Hee Jin worked with f(x) as art director at SM Entertainment. 

It looks like the two former co-workers are maintaining a great relationship even after all these years!
