Nicole Richie's daughter, Harlow Madden, had a star-studded birthday bash in LA yesterday. They celebrated at the children's play space, The Coop, where Ashlee Simpson's son Bronx partied for his big day last year. Gavin Rossdale brought Kingston and Zuma along for the fun event and Tobey Maguire's wife, Jennifer Meyer, arrived with kids Ruby and Otis.
Harlow actually turned four last week, but its been a busy month so far for the Richie-Madden family. Nicole attended the Golden Globe Awards on Sunday and promoted her new reality series, Fashion Star, at the TCAs in Pasadena last weekend. Nicole and Joel didn't miss their daughter's big day, though, since they honored Harlow on Twitter. Nicole joked, "In case your'e wondering if I had my child born on the same day as Mary J. Blige on purpose, the answer is H*LL TO THE YES" while Joel wrote "Happy Birthday to my little girl. I'm so proud of her. Life is good. :)"
