(usmagazine.com) - Nicole Richie celebrated her pregnancy with a Wizard of Oz-themed baby shower at the Beverly Hills Hotel Sunday. It was hosted by her mother, Brenda, her sister, Sophia, and her long time pals, Paris Hilton and Masha Gordon.
Richie, 26 - who is due in January - arrived in a blue-trimmed white dress around 1:30 p.m. 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.
Party planner Mindy Weiss threw the bash, a source told Usmagazine.com.
"The shower was really cute," Hilton told Us. "We had a Wizard of Oz cake."
The 90 guests - including Lauren Conrad, celeb DJ Samantha Ronson and Aussie singer Sophie Monk (Benji Madden's fiancee ) - noshed on "little burgers and pasta," Hilton added.
The bash ended around 4 p.m.
"The shower was great," Conrad told Us. "It was really cute."
