NEWLYWEDS Kate Hudson and Chris Robinson are so hot for each other they barely noticed that it’s freezing cold in England, where they spent their honeymoon.

“We’re having the time of our lives!” ecstatic Kate told The ENQUIRER photographer who snapped these exclusive pictures of the pair on their honeymoon in London. “It’s a little cold but we’re having a ball.”

The 21-year-old actress daughter of superstar Goldie Hawn, Kate married Black Crowes rocker Chris, 34, on New Year’s Eve. Then the couple jetted off to London, where they spent their nights at London’s posh Athenaeum Hotel and their days shopping in trendy Notting Hill.

Kate — who starred in the movie “Almost Famous” — was almost unrecognizable as she wandered with her husband through the crowds in a winter coat and warm wool cap.

“The temperature dipped below freezing but Kate and Chris didn’t seem to mind. They strolled arm in arm and at one point Kate put her hand in Chris’ pocket to keep warm and gave him a kiss on the cheek.”

After their London visit, the lovebirds went off to a country house in Lincolnshire, where they’ll stay until Kate wraps her current film, the war drama “Four Feathers.”
