Jack Antonoff, wearer of many hats (both figuratively and literally) between Fun. and Bleachers, took to Twitter to question Billboard‘s investigation into the well-being of the former project. In the process, he dropped a bit of studio news.

Antonoff announced he’s been writing new songs in Los Angeles, some of them with Tinashe, who turned heads with last year’s debut album Aquarius.

Antonoff isn’t clear, though, as to what project it’s for. Is Tinashe working on Bleachers’ second album or Fun.’s long-awaited follow-up to 2012’s Some Nights?

And the songwriter had some harsh words about Billboard‘s new story on the future of Fun. Here’s what he had to say:

press has an obligation to get real sources — otherwise the world becomes super boring because who knows what’s honest

for example: sources say sinbad was eating out of the trash.
