On January 21st, Haha's mother uploaded a photo on her twitter and wrote,"wa~~~o~~ Yoongdeu(Okjung mom) and Haha (David) filming for Skull and Haha concert (in 2013)"

The photo showed Haha crossdressing as a woman, he is wearing a black dress with a pearl necklace, also wearing a short wig . Haha together with his mother posing with V signs while having bright expressions on their faces.

Haha seemed to feel embarrassed about this since he replied to her tweet with,"Mom..."

Netizen commented on the photo,"Haha's mom is so cute","He really looks like his mother","Haha looks funny in that dress", and so on.
