Fifth Harmony serenaded the MTV Newsroom on Tuesday (October 22) with "Who Are You" and "Miss Movin' On." And after singing, Ally, Camila, Normani, Dinah Jane and Lauren took 30 minutes to answer fan questions and share info about their upcoming tour with Demi Lovato... and they even gawked at some celebrity abs in the process.

The fivesome just released their Better Together EP, and it's currently sitting at #2 on the iTunes charts. 5H shared the inspiration behind the new music and their favorite song off the project.

"Collectively, it's 'Who Are You,' " Normani Hamilton said. "You just feel it."

Harmonizers sent in Vines, tweets and Instagrams, and lucky fans in the audience posed their pressing inquiries, like "What would your dream date be?" and "What Disney princess would you compare yourself to?" (Want the answers? Watch the video to find out!)

In between questions, things got a little crazy — shouts, whistling and a little bit of playful cat-fighting — all over a few six-packs. Abs, that is. The girls picked their choice man just by looking at a picture of their stomachs. It got a little rowdy, to say the least.

"Live from MTV" turned in a 5H fan hang sesh, with Harmonizers going back and forth with the singers, as they laughed and joked about things like the Kimye engagement and, uh, cannibalism.

Getting more serious, the dished on going on the road with Little Mix and Cher Lloyd for Demi's Neon Lights tour. They even talked about the new version of "X Factor" with Kelly Rowland. They gave more deats about their upcoming record (to be released next year) and more singles and videos on the way.
