The group, whose self-titled debut album dropped almost 14 years ago, released a teaser on Monday, revealing that the band is set to release their new album sometime next year.

"We're almost done with it and it looks like it will be out in 2017," Leto confirmed.

The 44-year-old entertainer isn't letting anything get in the way of promoting his new comic book epic, Suicide Squad, in which he plays Batman's long-time nemesis, the Joker.
