Posh and Becks continued their sunny summer weekend in Malibu hanging out with friends - including BFF celeb chef Gordon Ramsey - and their three children.

The whole family went to a party at a private home on Broad Beach in Malibu (with neighbors like Mel Gibson, Pierce Brosnan, and Stephen Spielberg). They and a group of about 20 friends enjoyed an hors d'ouerves buffet and drinks by the pool, delivered by a staff of five uniformed waiters. The party was spread out over three different balconies of the multi-million-dollar home.

The kids spent the entire time in the water -- boogie boarding on the beach and in the home's luxurious infinity pool.

But the activity of choice was PDA for David and Victoria! An X17 photographer on the scene tells us: "David and Victoria were so in love. They were hugging and kissing and just all over each other the whole time. It was really sweet. And Victoria in her short-shorts and tank top look she’s 22! These two are seriously the sexiest couple in Hollywood."

And yes, there are even more pix of the soccer stud shirtless. Just click thru our monster gallery below. De-lish!
