So, Katy Perry fans spend more on merch than ANY other fan group

When it comes to global fandom, Directioners and Beliebers are generally considered the most die-hard and devoted in the world, but it looks like they've some competition on their hands.

According to new research, British fans of Teenage Dream singer, Katy Perry, actually shell over the most dough when it comes to showing their devotion for the star.

Conducted by Barclaycard, The Battle of the Fan research established that KatyCats are the most flush with their money and are more than happy to majorly splash out on Katy merchandise and concert tickets.

Flashing the cash big-style, KatyCats spend, on average, £1,627 or €1,860 to get their fix of Ms. Perry and her on-stage extravaganzas.

"We compared fans of some of the world's biggest bands and artists – those that started when we did in the 60s and those who have more recently risen to fame," explained Katherine Whitton from Barclaycard.

"What the findings have shown above all else is that the nation's love affair with music, and especially live music, is very much alive and well … whether you're a KatyCat, Directioner, Swifty or Little Monster," she added.

And while that's all well and good, the research concluded that KatyCats – We've tried hating that term BTW, but secretly we totally love it – have beaten Yeezy fans, Queen Bey's subjects and Ri-Ri's army of followers to the top of the poll.
