Nick Jonas is a busy man these days. The former JoBro recently announced a number of new tour dates for Fall 2014 and is dropping his new single "Jealous," on Sept. 8^th.

Oh, and opened the US Open Women's Final on Sunday by singing "God Bless America."

Striking out on his own solo career, Jonas will be touring the U.S. this fall. Several tour dates were uploaded to Jonas's official website this week. The announcement read:

"Pre-order Nick Jonas' album now and you'll get early ticket access to his upcoming club tour and an MP3 download of "Jealous" on 9/8! Upon ordering you'll receive your ticket access code and link to purchase tickets for the tour."

And it seems the youngest of the Jonas Brothers trio will be travelling from coast to coast. The dates include:

9/22 - Seattle, WA @ Showbox

9/27 - Mesa, AZ @ Virginia G. Piper Theater

9/29 - Houston, TX @ Fitzgerald's - Upstairs - PRESALE SOLD OUT

9/30 - Dallas, TX @ Trees

10/2 - Chicago, IL @ The Bottom Lounge - PRESALE SOLD OUT

10/3 - Minneapolis, MN @ Fine Line Music Café

10/5 - Pontiac, MI @ Crofoot Ballroom

10/6 - Toronto, ON @ Lee's Palace

10/8 - Boston, MA @ The Wilbur Theatre - PRESALE SOLD OUT

Additionally, Jonas will be releasing his new single, "Jealous," on Sept. 8 (Sept. 7 PST).

The single is a follow-up to "Chains," the first song from Jonas's new album which is set to be released Nov. 11, followed by the club tour.

MTV reported that Jonas opened up about "Jealous" in a recent interview with Ryan Seacrest and provided a little insight into where the lyrics of the song come from.

"I was out with my girlfriend the night before I wrote this song ... and I got heated," said Jonas. "I was doing all this fighting training for this show I just finished up, so I was ready to go. [But] I contained myself ... and I came in the next day to the studio and wrote this song."

In terms of men getting jealous about other guys checking out their girlfriends, the singer added, "A lot of people can relate with this, a lot of men, they don't talk about it, it makes them uncomfortable. But I think vulnerability is good and it's what makes us human."

In preparation for the "Jealous" release, Jonas warmed up his vocal chords by singing "God Bless America" at Sunday's US Open Women's Final match between Serena Williams and Caroline Wozniacki.

While Williams thrilled fans by winning the 2014 US Open title, Jonas couldn't quite keep his mind off of the rest of his big day ahead.

US Open was awesome! #jealous comes out in approximately 5.5 hours!
