Sept. 26 (UPI) -- Singer Jason Mraz teased fans with the potential of a "big announcement" Thursday.
Mraz posted a video to Twitter on Tuesday encouraging fans to keep an eye on his social media for the special announcement on Thursday.
"Thursday. Stay tuned," Mraz wrote.
The vague video left many fans speculating whether the announcement could be a new album or an appearance in the Broadway musical Waitress since he had previously recorded songs for Sara Bareilles' album What's Inside: Songs from Waitress.
Mraz parted ways with his longtime manager Bill Silva on Sept. 1 and possibly has been working on a follow-up to his 2014 studio album YES!.
