Look away, kids! Kate Hudson and rocker boyfriend Danny Fujikawa got frisky in a neighborhood park on Saturday, as Kate's son Bing played on the playground. Fujikawa grabbed the actress in a strong embrace and Kate caved, giving her boyfriend a smooch as they stood in the sandbox.

The pair have been dating since March, when we spotted them sharing a romantic dinner at Giorgio Baldi in Santa Monica. They've kept their relationship pretty low key, but they did appear on the red carpet together, in their first official appearance as a couple, at the LA premiere of Goldie Hawn's film Snatched earlier this month.

Kate and Danny bonded over Bingham, helping him on the slide, watching him as he climbed the fire truck play structure and admonishing him for kicking up sand. As the trio left the park, they looked every bit the happy family. Of course, Kate's tried twice before -- with Black Crows frontman Chris Robinson, with whom she shares son Ryder, 13, and with Muse rocker Matt Bellamy, Bing's dad. Perhaps third time's a charm?
