Hot couple Kate Hudson and Lance Armstrong who set Cannes ablaze with smoldering amour are back Stateside.

The lovers are more than close - they're glued at the hip.

Hawn spawn, Kate who's currently lensing Bride Wars in Manhattan, was missing her man bad when she summoned him to a late night shoot at famed Plaza Hotel.

"Lance showed up around 8 and told the crew he was there to see her," a production source told The New York Post.

"He went to the set and hung out."

In between takes, no doubt, they got Plaza Sweet.
