Ri arrived around 6 pm escorted by her assistant, went inside where she sat down alone at the table with Andrew. And hour and a half later, they left at exactly the same time - Rihanna out the back door (all our photogs where back there shooting her) and Bynum out the front.

Like her dinner with Jay-Z Thursday night, it may be just a friendly affair, but we're certainly glad to see Rihanna surrounding herself with strong, powerful men!
