Justin Bieber went to the recording studio on Thursday afternoon, and not only did we get a peek at his douche-tastic new hair, but we also got a glimpse at his underwear-clad buns!

Bieber was skateboarding with some pals outside when his booty popped out, and while he's pretty good at kickflips and other tricks, it seems like he's still struggling to find gym shorts that fit. No complaints here -- we love it when the 21-year-old pop star shows some skin!

Bieber met up with Skrillex at the studio, so we're very curious to see what music the duo come up with next. Their last tune, “Where Are U Now" is currently number 15 on the Billboard Hot 100 chart, and the music video for the song is expected to drop today, but we haven't seen anything online yet.

Back in April the Biebs revealed to Ryan Seacrest that his split from Selena Gomez inspired most of his new album, "It was a long relationship that created heartbreak and created happiness and a lot of different emotions that I wanted to write about," he said. "There’s a lot of that on this album."

We can't wait to hear more!
