One Korean funny lady took to Instagram to reveal her K-pop bias. 

Comedienne Lee Gook Joo revealed that she is a hardcore fan of the idol group B1A4.

"B1A4 sent me a heart so I sent them one too," Lee wrote on her Instagram Dec. 8, along with a picture.

The picture is a screenshot of the Snow App. With the photo application, Lee took a snapshot with a specialized frame making it look as though she was posing with the B1A4 members. The B1A4 members in the picture are making hearts with their hands.

Lee has always been known to be a hardcore fan of B1A4. She had attended their concert in September and posted a picture with them, and sang B1A4's songs endlessly on the MBC entertainment program "I Live Alone."

The B1A4 members and Lee first met through a radio program and have kept in touch ever since.

The group released their first Christmas song "It's Christmas" on Dec. 10.
