OK… who ever didn’t see this one coming, put up your hand. I mean honestly… it was a sure bet. Sorta like how Kim Kardashian got butt implants!

Kate Hudson and Owen Wilson have broken up, a source who knows the pair tells PEOPLE.

“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.

“He seems very happy,” Owen’s younger brother, actor Luke Wilson, told PEOPLE in April, while older brother Andrew Wilson called Hudson “the world’s most beautiful tomboy … She’s a great person.” ~ People Magazine
