A glowing Nicole Richie was joined by ex-BFF/possible future sister-in-law, Paris Hilton on Friday night to help their significant others, Joel and Benji Madden celebrate the opening of their new DCMA store. Nicole has said she's not loving her new bodacious body but we think she looks stunning and healthy. Paris continued to talk about how serious things are with Benji, including joining him on their international tour next week — wow that was fast! We, however, were more interested in what Nicole had to say about baby Harlow. On how she spent her Friday night Nicole said, "My mom's with her. It's fun, but it's bittersweet because I don't like to leave her. And I always wonder, 'What is she doing?' I've checked in twice so far – and I've only been gone an hour! But this is my adult night so I'm excited to see what the night brings."
