Miley and her BFF Mandy Jiroux have posted another episode of their usually unwatchable "Miley & Mandy" show on YouTube.

While the girls are as annoying as ever (Miley can't stop making faces or stand still for a second!!), her super hot boyfriend Justin Gaston (whom Miley calls "Justie" and "Jussie-Wussie") performs his new song "You Make Me Happy" and it's really pretty good.

Although we have to wonder who he's talking about when he sings "If she makes me happy/Why do you really care?" Anybody have a guess?



Tell us what you think of the song after the jump.
