Dewy-eyed duo KATE HUDSON and OWEN WILSON, mattress shopping at Leeds in Santa Monica, test-flopped on a few, then zeroed in on a bouncy number called – are you ready? – the CelebrityBed! The cute-as-pie couple stretched side-by-side on the potential launch-pad of their love life, locked in embrace and – as shoppers gawked – started counting down to blast-off! Owen kissed Kate…Kate kissed Owen…then Owen yelped: “Hey!” – and flinched as an elderly lady smacked his butt and snapped: “STOP! If you want to do that, get a room. I DON’T want to watch this!” Kate, red as a beet, jumped up and apologized as the older woman rolled her eyes – but hot-to-flop Owen quickly started talking price with the salesman.
