Just a few weeks after wrapping up his Camp Rock 2/Jonas Brothers tour in South America earlier this month, the youngest Jonas brother is back in the recording studio, working in what he's termed the "beatlab" in his tweets. The above photo is one in a series of pictures that Nick Jonas has posted on his Twitter, showing him recording an as yet-unnamed project. Brothers Kevin and Joe have not been in the pictures, so it is unclear whether they are involved in the project.

Jonas has had a busy fall. Aside from finishing his tour, he wrapped a four-week run of Les Miserables at London's famed West End in June before reprising his role as Marius Pontmercy in early October for the 25th Anniversary Concert at The 02 arena in London. He also suffered a setback, as Disney canceled his show Jonas L.A. in November after two seasons. –ISHITA SINGH
