Fashion designer Nicole Richie's daughter Harlow has celebrated her fourth birthday with a 'Toy Story'-themed party alongside a number of celebrity guests.
Richie and husband Joel Madden celebrated their daughter's latest milestone at Studio City, California with a number of celebrity guests, reported US magazine.
The couple, who are also parents to two-year-old Sparrow, were joined by Bush rocker Gavin Rossdale, who brought along his and Gwen Stefani's children Kingston, five, and three-year-old Zuma.
Tobey Maguire's wife Jen Meyer, Sara Gilbert and Rachel Zoe and their kids also attended the event, which took place at the same venue where Ashlee Simpson and Pete Wentz threw Bronx Mowgli's third birthday.
Harlow's party was attended by 35 kids, who were treated to a visit from the Pixar animation movie's star characters Woody, Buzz Lightyear and Jessie. "Everyone had a blast and Joel and Nicole said it was their best kids party yet," a source said.
