Beyonce Teases New HBO 'World Premiere Event' Titled 'Lemonade'

The singer posted a 16-second clip on her social media accounts.

In the video, Beyonce, 34, is sporting blond cornrows -- similar to one of her looks in her latest music video "Formation" -- leaning on what appears to be a car. She cryptically says, "What am I gonna do love, what am I gonna do?"

There's no word on what "Lemonade" could be, but Beyonce's fans -- known as the Beyhive -- have been buzzing about it since last month, calling it a "short film."

ABC News reached out to the singer's camp, but so far no word back.

Beyonce is known for pulling off surprises. In fact, her most recent self-titled album was a surprise to fans when she released it in 2013. She also released her first single, "Formation," from her latest album without notice.

The singer is currently on her Formation World Tour, which hits the U.S. in Miami on April 27.
