Hollywood actress Charlize Theron, who stars in the hit film "Mad Max: Fury Road," also in Japan, celebrated her 40th birthday on August 7th (local time). She held a birthday party at her West Hollywood home, where many of her celebrity friends came to celebrate. Among those attending the party were Emily Blunt and her husband, John Krazinski, who co-stars with Charlize in next year's film "The Huntsman," comedian Chelsea Handler, and Johnny Knoxville. Both Emily and John were dressed casually in denim pants, and John entered Charlize's house carrying a large box that appeared to be a gift. Charlize recently split from her fiance, Sean Penn, in June. Then, earlier this month, it was reported that Charlize adopted a baby girl, August, of African descent, who was born this year. Charlize adopted a baby boy, Jackson, from her native South Africa in 2012, and it seems that this time they were able to celebrate her birthday as a family of three.
