Beyoncé posted a teaser video Saturday showing a "world premiere event," titled "Lemonade," which will air on HBO this later this month.
The teaser includes a shot of the singer sporting braids and a fur coat.
"What am I gonna do love, what am I gonna do?" she says.
Many fans have speculated that "Lemonade" is an album film. The singer has not commented. Beyoncé is expected to drop a new album later this year but has not revealed a release date.
Beyoncé dropped lemon-themed hints on social media last September, but offered no explanation.
The singer debuted a surprise first single and music video, "Formation," from her upcoming album in February and performed the track days later at the Super Bowl 50 Half Time Show. She later announced an upcoming world tour.
Beyoncé released her last album, Beyoncé, as a surprise in 2013.
HBO aired the 2014 special "On the Run Tour: Beyoncé and Jay Z," which showed the singer on tour with her husband, as well as the 2013 documentary"Beyoncé: Life Is But a Dream."
"Lemonade" will air on HBO on April 23 at 9 p.m. ET.
