Nicole Richie and Harlow grabbed coffee and snacks together yesterday in LA. Harlow practiced her walking on the way back to the car, but she isn't the only one who has been getting physical lately. Nicole was shaking it during Jay-Z show on Sunday, and she twittered about how sore she was after working up a sweat. Joel Madden is still in Australia with Benji, but things went a little sour when he walked out of an an offensive radio interview in Melbourne because he wasn't in the mood to play games on air.
