The hashtag is believed to have been started by girl band Fifth Harmony fans, some of who are reportedly enjoying the backlash 5SOS have received for their Rolling Stone interview, reports

Extracts from a recent chat with the 5SOS - Luke Hemmings, Calum Hood, Ashton Irwin, and Michael Clifford - were released online and fans were left shocked by some of the comments, in particular those about sleeping with fans.

The fans seem to have taken particular offence to some Fifth Harmony fans - known as harmonisers - who have brought up Irwin's self-harming history and his father leaving.

One supporter wrote: "#5SOSIsDeadParty Harmonizers bringing up Ashton's past but can they bring up 5harmony's future?"

The 5SOS fans also took to Twitter to thank One Direction's fans for their help.

"When u know Directioners and 5sosfam will always support each other," a delighted Twitter user wrote while someone else wrote: "When 5H tries to bring 5sos down. But they forgot that fandoms that sticks together, SLAY together! #5SOSIsDeadParty."

In the interview, which saw the band posing naked on the cover, Hemmings talks about having sex with lots of girls while on tour - something which has caused upset.

The excerpt reads: "Hemming says they took full advantage of the attention. They were wildest on their easy tours, when they'd go to bars to mingle with fans after shows."

"'When you put four young dudes on a tour bus, playing theaters, then arenas, you're going to have sex with a lot of girls, I guess, says Hemmings. 'We had a good time.' Multiple girls in one night? 'Feel like I shouldn't say' he says with a smirk. 'You could say the possibility of this is high… the possibilities are endless.'"
