Joe Jonas is a Workout Wonder

Joe Jonas throws on a simple white tee and a pair of plaid shorts before hitting up the gym in Los Angeles this past weekend. The 19-year-old Jonas Brother wore a Los Angeles Dodgers baseball cap and carried around a smoothie cup.

Today, on the JoBros‘ official blog, they implored fans to pick up the new Demi Lovato CD called Don’t Forget.

They said, “Just wanted to let you know that Demi‘s new CD is in stores TODAY!!! We are so proud of our friend. She is an amazing singer and musician. Also, we want you to know that we were able to co-write and co-produce 6 of the songs on the CD. There is even a duet we can’t wait for you to hear.”
