Hudson and Wilson's romance heats up in Miami

Kate Hudson looks serious about her renewed romance with Owen Wilson, after celebrating her 29th birthday on a lunch date with the actor and his parents.

The blonde beauty celebrated her big day on Saturday, when she dined out with her 'You, Me & Dupree' co-star and his family at Gloria Estefan's restaurant Lario's in Miami, Florida. And the couple appeared to be having a great time.

A source tells People.com: "The four of them sat away from the crowds and had a blast. Kate and Owen looked very happy and were talking up a storm to Owen's parents."

They then enjoyed a night out with Hudson's girl pals at the city's Shore Club, where the couple kissed and "were very sweet looking". The source adds: "It was super lovey-dovey."
