Happy Birthday, Kingston Rossdale!

Expectant mommy Gwen Stefani and husband Gavin Rossdale throw a birthday party for their son, Kingston, in Culver City, Calif. on Sunday. Kingston turns two-years-old on Monday!

There were ponies! And cowboys and cowgirls!

It looks like Joel Madden was there with his daughter Harlow, 4 months, but no girlfriend Nicole Richie. Victoria Beckham was also there with her youngest son Cruz, 3, but no husband David Beckham. Cruz dressed in a monkey costume!

HAPPY BIRTHDAY, KINGSTON!
