The Wilsons were promoting their new movie The Wendell Baker Story on New York's Q104.3 when they were asked about the status of brother Owen's romance.

Luke joked about welcoming Hudson into the family, prompting presenter Shelli Sonstein to push him further, asking if the couple were seriously planning to marry.

Director Andrew then said, "I thought they were married already."

Representatives for Owen Wilson and Hudson insist the You, Me + Dupree co-stars were not husband and wife.
