Charlize Theron was delighted her son thought she looked ''pretty'' at the Oscars last night (02.03.14).The 38-year-old actress' little boy Jackson, two, watched her get ready for the Academy Awards and was very impressed by her black Dior gown and 31-carat diamond necklace. Speaking at the Fame & Philanthropy Post Oscar party, she told People: ''I got my first 'mama pretty' tonight, so it was a slam-dunk for me. I'm very happy right now. [Motherhood is] really good.'' Charlize was accompanied to the post-ceremony party by her boyfriend Sean Penn, 53, where they were reportedly spotted holding hands and sitting ''very close'' in the VIP area. On Thursday (27.02.14), the couple attended Pharrell Williams' pre-Oscars party at Eveleigh in Los Angeles and couldn't hide their affection for one another. An onlooker said:''Watching Charlize and Sean get down! Both so hot. Charlize and Sean are so gorgeous together, a natural couple.'' The 'Young Adult' star was seen resting her head on the 'Milk' actor's shoulder, and they also joined in with dancing to tracks from Pharrell's new album 'G I R L'.
