Fifth Harmony + More Hit Philly for Jingle Ball [PHOTOS + VIDEO]

The Philly edition of the 2014 Jingle Ball Tour hit the City of Brotherly love on Dec. 4. Fifth Harmony were there. Avril Lavigne, Flo Rida, Robin Thicke and more were on site, too.

Fifth Harmony, who are always full of boundless energy and who are, well, 'Better Together,' talked about how to survive performing outside in the cold, like they did last Thursday, and about how much they love their Harmonizers aka fans.

We also found out their fave McDonald's combo meals and which superheroes they love. The ladies took these silly questions seriously and thought about their answers. It made for an entertaining interview.

You have to watch to find out what else the gals said -- we're not doing all the work for you, Crushers! We kid, we kid. It's just that Fifth Harmony are so cute. We fall under their spell when we watch their video interviews.

In a separate video chat, the ladies once again espoused their love for Harmonizers and shared some of the awesome fan gifts they've received, like a mixtape with an explanation as to why each song was chosen and a signed, vintage Selena (not Gomez, mind you!) poster. Sweet, right?

The ladies of Fifth Harmony, as stylish and as sexy as ever.
