The powerful pair duet on Alicia's Put it in a Love Song, from her album The Element of Freedom.
Against a backdrop of dilapidated buildings, washing lines and curious children, Beyoncé rocked in floral high-waisted hotpants and a printed cropped shirt.
Alicia opted for a sheer floaty white dress with voluminous hair as she filmed scenes on the roof of a house in Morro Santa Marta in Rio.
When the pair shot scenes together, Alicia changed into a printed monochrome mini, with gold strappy heels and colourful hair accessories.
Can't wait to see the finished product, ladies!
