With only hours to go before the release of their sophomore studio album 7/27, the five girls of Fifth Harmony have been busy bees. Camila Cabello, Ally Brooke Hernandez, Dinah Jane Hansen, Normani Kordei and Lauren Jauregui have been all over the place promoting the latest project, stopping at some of the biggest spots, including the Billboard Music Awards last Sunday night, and on Monday they took a spin around the ballroom as they gave the folks at Dancing with the Stars a live performance during their season finale, and we gotta say that we give their song "All in My Head (Flex)" a big old 10!

In the clip below of the performance, the girls strutted on the stage in their sparkly dresses, and they looked like they were having a blast doing some freestyle choreography.

According to MTV, the gals have been teasing the project for the last couple of weeks with a release of a music video for the promotional single "Write on Me," and then with the performances of the track "All in My Head (Flex)" at the BBMA and then the DWTS finale.

With the release of the album just around the corner many have been trying to make sense of the album title, as the date 7/27 is not the release date, which many might have originally thought. Instead, according to Rolling Stone it is actually the day that the quintet was brought together as a group on The X Factor.

In addition to that, Jauregui also mentioned that the title could also be seen as a reference to a 727-jet plane and the girls desire to "take off" with this album.

From the good reviews we are hearing about the project, this could definitely be the take off they have been looking for. Entertainment Weekly gave the album a B rating, and used words like "uber-catchy," and said that one of the tracks, "Not That Kinda Girl," is "one of the best songs they've ever recorded."

However, the site does warn the girls not to take themselves too seriously, because it is when they try to proclaim their maturity that they end up losing the fun vibe that they are known for.
