Songstress Hayley Williams, of Paramore fame, has revealed that she is upset to think that someone leaked details of her band's forthcoming co-headlining tour with Fall Out Boy, but is so excited about the run of dates. 

In a series of posts shared via her official Twitter page earlier today (January 9), Williams explained that she was really disappointed to see that the news had been unveiled before the bands had the chance to make an official announcement:

"Yes. It's happening. Us & FOB coheadliner. Sucks some bonehead leaked it. We wanted to surprise you guys. Surprise, I guess! #MONUMENTOUR. Anyway. The same bonehead that already leaked the vid will surely be reposting it at it's INTENDED time pretty soon. So look out for dates."

The flame-haired frontwoman added: "Lastly, thank you to both FOB & Paramore fans for begging us for years to make this tour happen... 'Bout damn time. This is monumental."

The first concert will take place on June 19 in Connecticut and it will conclude with a performance in California on August 17. Tickets for the dates will go on general sale later this month on January 17.
