Troye Sivan enlisted some seriously sexy company for his music video for the single One Of Your Girls. In a twist, Troye plays the girl here, while one of our favorite stars, Ross Lynch, plays the boy. And boy, what a boy. Ross Lynch has hardly hidden his body from the world in his previous roles. We got to see his tight, twink body and plump ass in his first grown-up role, My Friend Dahmer. But since then, Ross has hit the gym in a serious way, and he stopped the pesky habit of shaving his torso. That leaves us with a shredded jock Lynch complete with a gorgeous happy trail, leading to the promised land! The music video for One Of Your Girls is filled with close-ups of Lynch's crotch, which is positively poured into his jeans. Throw in Sivan's gender-bending sex appeal, and One Of Your Girls is one for the record books!
