Owen Wilson and Kate Hudson spent Easter weekend together in Miami – and this time, the on-again duo were joined by Hudson's son, Ryder, for a holiday bike ride.

After getting in some sunbathing, Hudson (accompanied by Ryder on one bike) and Wilson (with another young boy) rode through the busy streets of South Beach on Saturday before stopping for Starbucks on the less-crazy Biscayne Bay side of town. Mother and son even wandered into a drug store and a video store, where they picked up a new movie.

"They looked like a family on an afternoon outing, taking advantage of the balmy weather and doing some errands," says an eyewitness.

Wilson is due to start shooting more Marley & Me at the South Florida Sun-Sentinel in Fort Lauderdale Monday.
