Shia LaBeouf admits that he went on one date with Rihanna. Shia and Rihanna met through a stylist back in 2007, but according to LaBeouf didn’t have any chemistry. The pair never made it to date two, according to Playboy. We’re really learning a lot about Shia and co-star Megan Fox thanks to this Transformers movie. We know Megan is bisexual, Shia isn’t well-endowed and now that there’s no “spark” between RiRi and LaBeouf.
