Enjoying each other's company in Australia the last several weeks, Kate Hudson
, 27, and Owen Wilson
, 38, shared bike rides and walks on the beach. Now that they're back in the States, they're not letting jet lag cool their romance. On March 30 the previously low-profile couple were anything but shy over lunch at Santa Monica's Ivy at the Shore restaurant. "From the second they walked in, they were all over each other," says a witness. "Kate even [sat] on his lap to give him kisses." The pair's new openness reflects a "natural progression" in the relationship, says a friend. (Hudson, mom to 3-year-old Ryder, split with husband Chris Robinson last August.) Now the romance even has the Wilson family seal of approval. "He seems very happy," says Owen's younger brother Luke. "[Kate] is a very nice girl." And a keeper. "Owen has realized what a great thing he has," says the couple's friend. "They're having fun, but things are definitely getting more serious."
