ok so from the very little information i saw, apparently these are paparazzi(?) photos taken on the 2nd day of LEGEND MM(which took place on momo's actual 21st birthday) they weren't there for babymetal but for momoko's dad(Hanamaru Hakata is a well known comedian)
all the information is very murky, if i could tell you how these photos were published in the first place considering they're paparazzi i would tell y'all馃槶馃槶
