Happy Birthday, Kingston Rossdale!

Kingston Rossdale turns two years old today. But the son of Gwen Stefani and Gavin Rossdale has already celebrated his birthday is style.

Yesterday, Kingston's parents threw him a party that includes ponies, cowboys, cowgirls and a number of celebrities.

Joel Madden showed up with daughter Harlow, though Nicole Richie was nowhere in sight. Victoria Beckham was also there with her youngest son Cruz, who arrived to the festivities in a monkey costume.

We wonder what the celebrity fashion police would say about that.
