Still not ready to go public with their rekindled romance, actress Kate Hudson and Owen Wilson celebrated the actress' 29th birthday in Miami this weekend enjoying some quality time with Wilson's family.

Hudson, who turned 29 on Saturday, "looked very happy" in the company of old/new flame Owen Wilson and his parents while having lunch at Gloria Estefan's restaurant Lario's on South Beach.

"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," a source close to the couple was quoted by People.com as saying.

After the meal, the foursome ordered a cake which was festively presented to Hudson with a candle in the middle, the source added.

Later in the day, the two reunited lovebirds were spotted partying with some of Hudson's friends at Ago at the Shore Club before enjoying a hand-in-hand walk back to the Skybar, where they were photographed getting cozy and looking "super lovey-dovey" together while lounging on a poolside bed.

Prior to her Miami trip from Boston, where she's been filming her new movie "Bride Wars," the actress celebrated her birthday on the set, by ordering pies for everyone in the cast and crew.

Wilson, 39, and Hudson, who met while shooting "You, Me and Dupree," started dating in 2006 but kept their relationship a secret until early 2007 when the actor visited Hudson on the set of her film "Fool’s Gold" in Australia. However, by the end of May, the two went their separate ways. In August 2007, Wilson was rushed to the hospital after attempting to commit suicide.

The first rumors of a possible reconciliation between the two emerged this year in late February when Wilson was seen driving his silver Toyota Prius away from Hudson's Pacific Palisades home, while the actress was spotted entering Wilson's Malibu estate later that day.

Most recently, Wilson and Hudson got together for Easter also in Miami where they were seen riding bikes with actress' son, Ryan, having coffee and picking up some videos at a local store.
