JYP just released a M/V for his new song, ‘Who’s your mama?’. The M/V also features Jessi rapping powerfully to JYP’s new song about booties. In the M/V JYP is seen to be observing and singing about how important booties are. It is not an everyday thing that we see JYP perving on ladies in the gym as well as such a huge amount of booties in 4 minutes. Oh yeah, he also walks backwards on a treadmill (do not try that at home).
