Nicole Richie kept a low profile behind her hat and sunglasses in LA yesterday, but the details of her upcoming baby shower have been publicly broadcasted. Nicole's party will be this Sunday and instead of gifts, she and Joel have asked their guests to donate useful baby items to the Richie Madden Childrens Foundation, an organization they started to help mothers in need. As for the party itself, Paris will play hostess with their mutual friend Masha even though Hilton recently admitted that she's a little out of her element. She said, I honestly don't know what you play at a shower. Maybe I'll find a book or something to get some ideas."
