5 Seconds of Summer's new single is officially out!

Luke Hemmings Is Finally 19!

The Australian band kicks off the North American leg of their Rock Out With Your Socks Out Tour tonight, July 17, in Las Vegas, but aside from that they've been doing some phoners for various radio stations premiering their new tune "She's Kinda Hot," which they penned with Benji and Joel Madden as well as their other long-time collaborator John Feldmann.

"She's Kinda Hot" has that typical pop/punk sound expected of the band, but holds a rockier edge. Plus, the lyrics dive deeper than thinking a girl is "kinda hot." The song is actually an anthem for those who will not conform to others' standards.

A really strong line in the song is, "When you've got bigger plans that no one else understands, you've got a shot though."

The band is totally stoked the song is out now and Ashton Irwin even has his "fingers crossed" the song will be liked.

"This is the first single from our new album, been waiting so long for you to hear it!" they gushed on Twitter.

It can be bought on iTunes and played on Spotify. Plus, it looks like it'll be added into various radio stations' rotations too.
