When Charlize Theron and Seth MacFarlane were spotted leaving Beverly Hills hot spot Matsuhisa on Sunday night, relationship rumors took flight. But a source says the two aren't an item -- because the blonde beauty isn't Seth's "type."

Whatever that means.

E! News reports that the two "[definitely] aren't dating" because a source says Theron -- named the sexiest woman alive by Esquire in 2007 -- simply isn't the erstwhile Oscar host's proverbial cup of tea.

Last month the 'Family Guy' show runner split with 'Game of Thrones' cast member Emelia Clarke, who's no ugly duckling either. But come on. Have you seen Charlize Theron? If she wasn't shielding her face from paparazzi in the photo above, the camera would have shattered from her sheer magnificence.

So the two are just friends. Charlize is, however, starring in MacFarlane's next project, a comedic Western titled 'A Million Ways to Die in the West' -- not to be confused with a million impossibly high standards.
