Kate Hudson Celebrates Birthday With Her Sons

Kate Hudson spent a low-key day in New York Friday, celebrating her 34th birthday with two of her favorite guys -- her sons!

The Almost Famous star was spotted in Manhattan's Tribeca neighborhood, looking beautifully casual in jeans and a sweater.

The actress carried her 21-month old son, Bing, in a sling.  His dad is Hudson's fiancé Matt Bellamy.

Walking alongside was her too cool nine-year-old, Ryder, son of Kate's ex-husband Chris Robinson.

With Bing now a toddler, Kate is back to a full workload.  She's just wrapped an HBO movie, Clear History, with Mad men's Jon Hamm.
