That's sent South Korean media into a frenzy of speculation that there's a new baby in the ruling Kim dynasty.
Video broadcast Dec. 17 showed Ri Sol Ju wearing a billowing black dress that covered what appeared to be a swollen belly.
Rumors swept Seoul and Pyongyang that she was pregnant, although it was difficult to tell for sure from the images. There has been no official word from Pyongyang.
But Ri was shown by state TV at a New Year's concert wearing a tighter dress and looking noticeably slimmer. That's causing more speculation in Seoul that she may have given birth.
