Before transforming herself into a Jennifer Tilly/Diane Keaton hybrid at the Dedication premiere, Mandy sat down for lunch with the newly Manjoyable John Mayer. Well played, Miss Moore! I will say that these two could possibly make a cute couple, but Mandy was quick to deny that they are anything more than friends. She said, "Oh my goodness. John and I have been friends for years, no romance." For now I'm happy to see Mandy stick with her acting and singing, including this great cover of Rihanna's "Umbrella." As for Mayer's maybe love life, we'll update you on that in just a bit.
