"Wow! the response to #GuavaIsland has been quite overwhelming. So happy you guys felt the beauty in this film!" the singer-turned-actress wrote on Twitter on Wednesday, along with a musical clip from the film.
Rihanna went on to call Glover -- who also served as a writer and producer on the film -- a "true gem to the culture."
"I’m so proud of you and the work you put into making this film. I felt how close this was to you and your entire team!" she added. "Thank you for trusting me with this role!"
