Kate Hudson has already been playing mom to two sons for a few weeks now! Thirty-two year old Kate, who has a seven year old son, Ryder, from her marriage to rocker ex Chris Robinson, welcomed her new son Bingham Hawn Bellamy into the world earlier this month. Little Bing’s daddy is Kate’s 33-year old fiancé Matt Bellamy, front man of the British band Muse. (Guess Kate’s got a thing for musicians, huh?)

It seems like most celebs enjoy giving their children unique (cough, cough) names, but there is a sweet story behind Bing’s moniker—Bingham is Matt’s mother’s maiden name, and Bing was also Kate’s pseudo-stepfather Kurt Russell’s father’s name. The baby’s middle name, Hawn, is obviously a tribute to Kate’s mom, Goldie Hawn—Kurt Russell’s partner of nearly thirty years.

Seen here looking sporty while out on the town with son Ryder, Kate’s designer Persol sunglasses make a great addition to any outfit. Protect your eyes from the sun’s rays with the same shades. They’re available in black, Havana, or light Havana and are one of Persol’s best-sellers.
