Queen B gives Rihanna a run for her money in the raunchy snap...
Beyoncé's racy cover for next month's issue of GQ magazine has leaked on Twitter.
Queen B's image appeared online on Tuesday (8th January) ahead of its official release date, showing the Single Ladies hitmaker displaying her famous curves in a barely-there outfit.
The star - who gave birth to daughter Blue Ivy a year ago - dons a cropped, blue and white baseball top for the snap, which exposes the bottom of her breasts, completing her sexy look with a gold body chain and skimpy leopard print knickers.
Bey poses with her arms above her head, next to the headline 100 Sexiest Women of the 21st Century - and judging by the snap, the former Destiny's Child singer is a clear front-runner for the title.
