Ashanti won’t be going it alone…

The 40-year-old half-Afro-Dominican singer/actress has signed on to star in and produce the romantic comedy The Plus One.

Ashanti will play Lizzie, whose only request of her “Male of Honor” Marshall is that he doesn’t bring his hated ex Marie to her destination wedding. But lovesick Marshall brings her as his plus one, and Marie does everything in her power to wreck Lizzie’s big day.

Filming is scheduled to start in December in Florida.

The film’s director and additional cast members have yet to be revealed.

Ashanti most recently starred in the Sony Pictures Worldwide acquisition Honey Girls, which wrapped in March.

Her movie credits to date include Coach Carter with Samuel L. Jackson, The Muppets’ Wizard of Oz, John Tucker Must Die and Resident Evil: Extinction.

The singer, who has sold more than 27 million records worldwide, will be getting a star on the Hollywood Walk of Fame in 2022.
