Kate Hudson and Owen Wilson have split after several months of dating. Hudson was married to rocker Chris Robinson when she and Wilson started dating. They then filed for a divorce

“They’re still friends,” says the source, adding that the two split just before Memorial Day weekend.

The cause of the breakup wasn’t immediately known.

Wilson, 38, and Hudson, 28, who starred together in 2006′s You, Me and Dupree, recently had become increasingly open about a relationship that began quietly last fall and developed across many time zones. They were spotted strolling the beach in Australia (where Hudson was filming Fool’s Gold with Matthew McConaughey), nuzzling at a Santa Monica restaurant, kissing at Hudson’s April 19 birthday in New York, and getting cozy on vacation in Hawaii.

Who will be next on either of their radar? I would be interested in seeing Kate and Matthew McConaughey heat it up. And how about Jessica Simpson for Owen?
