There’s a lot of speculation over who Taylor Swift’s new song, “We Are Never Ever Getting Back Together,” is about. Joe Jonas of The Jonas Brothers would like to make it clear: it’s not about him. He says “I don’t think we’ve ever tried to get back together another time.” Taylor’s not saying who she wrote it about, but does say, “I ended up being inspired by a lot of really crazy sort of zero-to-a-hundred-and-then-hit-the-wall-and-explodes relationships, which are so fun to write about...really dysfunctional and not good, generally, but when you write about them it...it gives you a lot of inspiration.” If you had to bet money, a good bet would be either Jake Gyllenhaal or Twilight star Taylor Lautner.

Jason Aldean is preparing to share new music with his fans on Live on Letterman September 5th. That’s the CBS.com production that some stars do when they are scheduled to appear on the David Letterman show. It will stream at 8pm Eastern, followed by a performance on The Late Show with David Letterman. Meanwhile, his new song, “Take a Little Ride,” could be nearing the top of the charts by then. According to Jason, “We obviously had a huge first week when the song came out, and we’re hanging in there! It’s my highest debut of any song—ever!”

Justin Moore’s career has taken him to a lot of places he’s never been before, and as his new song, “Til My Last Day,” continues it’s climb up the charts, he’s getting set to hit the road with Eric Church on the Blood, Sweat and Beers tour. But there’s still one place he really wants to go: “Unfortunately I have not been able to do a USO Tour overseas. But it’s definitely something I would like to do at some point. I think it’s a small way that we can give back to our troops that have given so much to us on a daily basis.”

Jake Owen is on tour with Kenny Chesney and Tim McGraw right now, but he’s looking forward to November, when he and his wife add a daughter to their life. Jake says Lacey is rockin’ the baby bump: “She looks great! She’s just happy and smiley—there’s something beautiful about a woman that’s pregnant. It’s cool. This is a really cool time in our life because it’s the last few months before we have an addition to our family—and it’s three of us! So it’s gonna be cool.”
