Los Angeles: `Snow White And The Huntsman` star Charlize Theron thew a superhero themed party for her son Jackson`s first birthday.
The 37-year-old actress celebrated the birthday at the Coop, a play space for children, in Studio City, Los Angles, where Jackson`s friends enjoyed Spiderman cupcakes and special appearances by Wonder Woman and Batman, reported Us magazine.
"It was a really mellow party. Charlize is the nicest person on earth. She`s gorgeous and relaxed and sweet. Charlize absolutely adores (Jackson). They have the most wonderful relationship.
(Jackson) was jet-lagged, so when everybody sang `Happy Birthday,` they had to whisper it. She didn`t want it to be really loud," a source said.
