Charlize Theron [1] hit the gym with her little man, Jackson Theron, in LA on Monday. The actress may have skipped out on all the Golden Globes madness on Sunday but she did make headlines on Saturday when she showed PDA with new love Sean Penn [2] at his Help Haiti Home charity gala [3] in LA. The two cuddled and kissed during the dinner, and Sean hinted that Charlize inspired him to give 65 of his discarded guns to artist Jeff Koons [4] to be auctioned off at the event. Sean said that "a strong woman who happens to be from South Africa" inspired him to make the piece of art, which was sold for $1.4 million to Anderson Cooper [5].
