The girl group will perform two tracks, including their hit single, "Miss Movin' On," off their EP Better Together, out Tuesday (October 22).
Following the performances, Normani, Camila, Ally, Lauren and Dinah-Jane will sit down with MTV News' Christina Garibaldi, as well as a studio audience of lucky Harmonizers and talk all about the inspiration behind their six-track EP, their upcoming tour with Demi Lovato and answer your questions.
"We'll be answering your questions live. All you have to do is Vine, Tweet or Instagram your question using the hashtag #Ask5H," Fifth Harmony said in an Instagram video.
Their Better Together EP is currently sitting at #2 on the iTunes charts, and the girls just couldn't contain their excitement, posting a Vine video of themselves screaming in an airport with the title, "NUMBER TWO OH MY GOSH!!!!!!!!"
The "X Factor" alums enlisted the help of some of music's biggest names including One Direction producer Julian Bunetta, who revealed to MTV News earlier this year what he hopes to have captured on the girls' debut.
"I would hope that every girl would just put it on, when they're getting ready to go out or when they're in their car going somewhere and they just want to have a great time," Bunetta said. "That's what I want this album to be."
Don't forget to tweet, Instagram or Vine your questions for Fifth Harmony with #Ask5H and see if your question gets answered during "Live from MTV" today at 3:30 p.m. ET.
