Nicole Richie

Nicole and Joel took their adorable little girl, all dressed up in a party dress and red headband (Blair would be proud) to a Christmas party Sunday, where she rubbed elbows with Jessica Alba, Honor Warren and Rachel Zoe!

Nicole even got into the holiday spirit, getting a snowflake painted on her cheek!

This will be Harlow's first Christmas -- what do you think Santa's putting under the tree for her?
