He's working on his fitness!

Some celebs prefer isolated gyms over the outdoors but Justin Bieber did his best to debunk that theory when he went for a jog through the streets of Beverly Hills on Friday. Nice shoes!

The 20-year-old pop star has recently been making waves with everything besides music, partying in Ibiza and causing a stir among Hollywood's elite to name a few, yet still finds time to get a good workout in.

We're sure he's back to work since he's had a while to get the good times out of his system. The world's waiting for a new album!
