Apink's Eunji had a surprise for her fans on her Radio show 'KBS Jung Eun-ji's Gayo Plaza.'

On the December 27 show, Eunji briefly turned on the live radio to let fans watch her sing. She covered the song 'Let it Go' from the movie 'Frozen.'

As this wasn't planned in advance, many fans were surprised and loved to watch her sing.

Some of the comments included:

"Singing genius Eunji..."

"It's almost identical to an instant live sound source"

"okay queen, Elsa needs to watch out"

"Listening to it in the car....it was so good❤️ Our DJ All-round DJ"

"omg her voice is on fire!!!"

"KBS is so lucky to have her as one of their DJ"

Meanwhile, Apink will be holding a fan-meeting 'Pink Eve' on the 31st December 2021 to celebrate their 10th debut anniversary. 

The group is also preparing for a comeback in February 2022.
