It was a family affair!

Kate Hudson headed to the park with newborn daughter Rani Rose, her sons Ryder and Bing, and her boyfriend Danny Fujikawa over the weekend, and it looks like the actress is already getting her pre-baby body back less than a month after giving birth. How do these celebs snap back so quickly?!

The bubbly blond has her hands full with three young children, but that doesn't mean she's taking any time off work!

In fact, she just signed up to star in the new movie Blood Moon alongside Craig Robinson. The flick is about a girl who possesses strange and dangerous abilities, and escapes from a mental asylum in New Orleans. Production doesn't start until next spring, so she's got ample time to enjoy maternity leave.

If you want a peek at her new little princess, just head over to her Instagram page.... the videos she posts are downright adorable, like this one!

Kind beautiful man, your pure love is such a gift #daddysgirl 💕
