The 37-year-old Oscar winning actress sparked rumours she is dating funnyman Seth MacFarlane after they were spotted on a dinner date at Sushi restaurant Matsuhisa in Beverly Hills on Sunday night (07.04.13) but they are just friends and were discussing his upcoming movie `A Million Ways to Die in the West", which the South African beauty is set to star in. A source told E! News: "(They) def aren`t dating. She is not his type. "They are just friends. Charlize is single." Charlize and Seth, who split from `Game of Thrones` actress Emilia Clarke recently, became firm friends during rehearsals for the Academy Awards in February, which the `Family Guy` creator hosted and she performed a dance routine with Channing Tatum. The duo were previously said to have been "very flirty" with each other at a post Oscars bash in Hollywood on February 24. Charlize has been focusing on raising her son Jackson, two, who she adopted last year. The actress`s last known relationship was with Irish actor Stuart Townsend. The couple dated for nine years until 2010.
