THE KATIE & JAMIE SHOW: PDA ALERT! For your eyes only . . .

SO THEY still haven’t officially confirmed they’re a couple, but KATIE HOLMES and JAMIE FOXX sure seem to have become less concerned about who sees them together. Their latest public display of affection was snapped during a romantic holiday aboard a yacht in Miami and it left little doubt in anyone’s mind: these two are an item with a capital “I”. The pair spent time having drinks and hanging out on the top deck, listening to music and chatting, a source said.

“One morning they ate breakfast alone on one of the decks, where they were smiling and laughing throughout the meal.”

At one stage Katie (40) even put on a private dance for her 51-year-old beau.

“Their relationship seems so much more serious this year,” the insider adds. “Katie and Jamie keep having public dates, and although they try not to be photographed together they’re clearly not as concerned about keeping their relationship private.”
