Nick Jonas Jealous song, along with "Chains," are signs that the young pop star is now a long way since his days performing with his brothers for Jonas Brothers. He stopped by "Complex" and talked about how he is now venturing into making his own singles, such as "Jealous" and "Chains."

His upcoming self-titled album, which will reportedly be out by November 21, will be featuring Mike Posner, Angel Haze, and fellow "Camp Rock" star Demi Lovato. Still, despite the fact that he is presently very busy with his work in the music industry, Nick Jonas' schedule is kept busy with an upcoming movie "Kingdom."

In fact, Nick Jonas has committed himself for the role that he is even undergoing heavy MMA training so that he could live up to his role in the upcoming flick. Perhaps this is the reason why Nick Jonas has gone from being adorably cute to becoming a buffed hunk.

Plus, Nick Jonas is also pretty busy with his skills as a live show creative director. He has been selected to be the creative director for Lovato's "The Neon Lights Tour."

Clearly, Nick Jonas has a lot on his plate lately, and it would seem that he is loving every minute of it.

Also, Nick Jonas also confirmed just last week that his "Jealous" hit will be the latest iHeartRadio "On the Verge" selection for the pop format. "On the Verge" has actually helped a lot of songs become huge hits today, such as Clean Bandit's "Rather Be" with Jess Glynne, Iggy Azalea's "Fancy", and Tove Lo's "Stay High." The "On the Verge" program guarantees the hits involved with it airplay from some of the nation's most high-profile radio stations, meaning that more people will be able to listen to it and love it, eventually adding up to the album's sales.
