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 and Dupree co-star and his family at Gloria Estefan's restaurant Lario's in Miami.

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."
