Kate Hudson & Matt Bellamy's Family Beach Day (PHOTOS)

Just over a week ago, Kate Hudson gave birth to her second son, Bingham Hawn Bellamy, and already the actress is out and about, spending the afternoon at the beach with her older son Ryder Robinson (with ex-husband Chris Robinson) and her future husband, Muse frontman, Matthew Bellamy.

The growing family left baby Bingham home while they spent the day in the sand. Hudson got her feet wet and her hands dirty as she built sandcastles with her older son and managed to squeeze in a little PDA action with her future hubby. Hudson revealed that she and Bellamy were engaged while on "The Today Show" back in April.

Although Bingham is the first child for Bellamy, it looks like he's had plenty of time to practice his daddy skills on Ryder. After Hudson departed the family outing, he and his future stepson took a stroll along the water and enjoyed the rest of the afternoon on the beach, just the two of them.
