KEY POINTS:
Nicole Richie had a Wizard of Oz themed baby shower yesterday.
The Simple Life star, who is due to give birth to her first child in January, invited around 90 guests to the party at the exlusive Beverly Hills Hotel.
Nicole's Simple Life co-star Paris Hilton hosted the bash along with Nicole's sister Sophia and the pair chose the theme because it is Nicole's favourite movie.
Paris, who was wearing a blue summer dress, gushed as she arrived: "I am so happy for her, it is really great. I can't wait for them to have the baby."
Nicole's fiance Good Charlotte singer Joel Madden, her mother Brenda, close friends DJ Samantha Ronson, The Hills star Lauren Conrad, Aussie singer Sophie Monk, Masha Gordon and Paris' sister Nicky also attended.
The party kicked-off at midday, with Nicole looking elegant in a simple black dress and oversized sunglasses.
She was greeted by life-size replicas of all of the Oz characters Dorothy, the tinman, the lion, the scarecrow and the Wicked Witch of the West, according to Us magazine.
Although Nicole and Joel are yet to confirm the sex of their baby, the couple reportedly received mostly blue gifts, suggesting they are expecting a boy.
One guest gave the soon-to-be parents baby trainers for a boy and a Tummy T Jack maternity shirt with a picture of a boy on the front.
Nicole, Joel and her family were the last to leave the party at 4.30pm.
Last week, Paris admitted she was worried about the baby shower and wanted everything to be perfect.
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.
"It's going to be really nice, with just us girls. Just Nicole's closest girlfriends and female relatives."
Joel recently revealed he can't wait to become a father, saying: "This is the most exciting thing that has happened to me, and to us."
