Are Emblem 3 and 5th Harmony in competition?

X Factor alums, Fifth Harmony and Emblem3, remain really close despite the fact that they were competing against each other last year! Recently, 5H and E3 reunited at B96's Pepsi Jingle Bash in Chicago! They hung out backstage and snapped some cute pics together. 5H's Camila tweeted, "I missed you boys so much... you guys will kill it tonight!" Emblem3 even sent them flowers! Awww!
