Jay Park sure does like to surprise his Jaywalkers! Just a few days ago, he uploaded a cover video to Travis McCoy and Bruno Mars' Billionaire. The singer/model/actor is already back and uploaded a surprise video for fans with a same title the popular American Idol song that went viral, Pants on the Ground. Though he's not singing to the song, he does show off his acrobatic side by trying to do a back-flip into a pair of jeans. Due to the fact that he can't perfectly make it in, he ends up doing a hand-stand and landing in the pants. He left the following message with the video,

"another suprise upload everyone Was at a photoshoot, wont reveal for what though lol ??????????? ???? ?? ??????? mystery???? ?????? ^^"

Jay mentions a mysterious photo shoot to which he participated in based on recreation though he can't reveal exactly what it was for. What do you think? [Thanks to everyone who sent in a tip]
