Owen Wilson is planning to propose to Kate Hudson, it has been claimed.

The comic actor - who has grown increasingly close to his You, Me and Dupree co-star since she split from husband Chris Robinson - was allegedly seen shopping for engagement rings with his mother at the Harry Winston diamond store in Dallas on Friday.

A source told the New York Post newspaper: "They were looking at a huge, pear-shaped, flawless diamond engagement ring."

Owen, 38, and Kate, 27, met on the set of the romantic comedy earlier this year and the actress - who has a two-year-old son Ryder - announced her split from rocker husband Robinson shortly after.

Though both stars have vehemently denied they began a relationship either before the split or after, they have been seen dining together frequently and Owen has visited the 'Almost Famous' actress at her home.

A representative for the actor has denied he was looking for an engagement ring, saying: "Owen's mother was looking for jewellery for herself."
